Try enabing the Develop menu so you can easily empty the Safari cache...
From your Safari menu bar click Safari > Preferences then select the Advance tab.
Select: Show Develop menu in menu bar
Now from the menu bar again, click Develop > Empty Caches
Quit then relaunch Safari to test.
If that doesn't help, back to Safari > Preferences. Select the Privacy tab.
Click: Remove All Website Data
It's aweful. Works fine for a few minutes to several hours, then the pages just seem to stop loading - progress bar gets 20 to 50% and it hangs. Emptying cache via the dev menu doesn't seem to matter. Sometimes closing the tab and opening a new tab does work, but it's faster and sure temp fix to quit and reopen Safari.
Also tried reseting Safari and that did not resolve the issue.
Chrome is starting to look really good as a primary browser now.
I have similar problem and till now i still can't resolve it.
Mine will stop loading when doing google search in the unified search bar. And will also happen intermittently if i go to www.google.com or www.youtube.com via the unified search bar.
My temporary resolution is to change the default search engine in Preference from Google to any other like Yahoo or Bings then the problem stop occuring. But i still want Google as my default search engine.
Not sure this is a good temporary fix, but since trying this mine hasn't failed and be interesting if it has any effect of any of your systems:
Another thread on the topic someone suggested the issue is the IP6 setting (System Preferences -> Network -> Ethernet or Airport -> Advanced -> Config IP6) changing it from Automatic to Local Link Only.
Don't know if this really fixed it, or if I've just not trigger the cause, but I've gone over 3 hours with out the need of quitting and restarting Safari since changing the setting.
Also the unified address search bar has another issue not directly related to this issue of Safari stopping. If you perform a search using the address/search bar, results appear and Google's form is correctly filled out. But if you then alter the search criteria in the Google form area, perform a search, click a result, and hit the back button, the initial search criteria used in the address/search bar are restored as the search criteria.
I am having a similar issue, I'm wondering whether or not the develop menu has anything to do with it since it generally only happens when im running the application with the "disable caches" develop option selected. I too have tried emptying all my caches to no avail. Glad some others are experiencing this issue as well but there's clearly a pattern here and this needs to be addressed.
Agree, Apple have screwed up something.
Safari regularly stops working when the wifi continues to work on ipad and iphone. It is only since safari 6 and mountain lion. Extremely frustrating.
If someone finds a solution please post it here.
I have tried to clear all website data, restart the macbook a few times, force quit safari, etc. but so far the problem continues. The website i am loading is different each time to try and vary the code it is loading and if i immediately test on another device that website works fine on another device. The quickest work around i have found is to turn off wifi on the macbook and turn it on again which only takes about 10 seconds but it drops the page you are working on so if entering text or something it is extremely frustrating when you lose it all!! It feels like i'm using a microsoft windows machine and having to fudge work arounds to get the stupid machine to do what it's supposed to be designed to do. Clearly not pleased.
Mine is doing the same thing. Rang apple support and they went through deleting the com.apple.safari.plist file or whatever it is. Started working then stoped. Tried switching to ethernet and it started working. Switched to WiFi. Stopped. Renewed DHCP Lease, didn't work. Deleted all remembered networks and passwords. Started working. Apple said to keep an eye on it and I thought for a bit it was fixed. Bout half an hour later stopped working again. Seems to be any secure sites, facebook, my Uni's website, checkout section when making an online purchase. Last night couldn't load the Apple discussion forum. I even reset my network back to factory default and set it up from scratch again. iPad and iPhone also work perfectly at same time on same network. Can't say I'm very happy either.
I'll just add an "Amen!" to all the descriptions preceding my post: Safari 6 *IS* dysfunctional and a step down, not up, from Safari 5.
I downloaded Safari 6 the day it was released, use my Macbook 10-12 hours daily in my business, and have yet to experience anything snappy, zippy, or fast about the new Safari. H/W specs of the "TARDIS", for whom it may concern:

We run Mac OS X 10.7.4 (Lion), with no immediate plans to buy Mountain Lion -- in two weeks' research re the Safari 6 issues, we've seen no conclusive proof the new browser's speed and handling issues are improved by an ML upgrade.
The only plugins used here are those standard with the system; no extensions; and we've never needed nor wanted any browser but Safari, from our first iBooks running Jaguar, to Powerbook G4 with Tiger, and now, the MB with Lion. Frankly, until we d/l'd Safari 6, our user experiences were pretty much flawless.
Now, not so much.
Apple engineers/developers need to note seriously the thousands of complaints scattered across the internet -- here, at social media sites, at Google users' forums, and at the various Mac users' forums. There is undoubtedly a problem with Safari 6 for a large and vocal number of users, if they'll only bother to examine the evidence.
Yep, I'm seeing the same problem. Rolling right along, viewing web pages, and then suddenly, Safari stops loading them. Progress bar gets about 20% and everything comes to a screeching halt. Sometimes using a new window helps. Quitting Safari and re-starting always seems to solve the problem. But I really don't enjoying going through my day having to re-start my browser a few times a day when I work as a web developer. *sigh* Apple, please help!
All, I hope I have a solution for at least some of you. Thankfully this worked for me and i have had no problems for three days now (when it was an hourly occurence before). I live in London and use Virgin Media as my ISP so I am not sure this will work for everyone but nonetheless here goes: I found online this problem may be linked to the wifi router's firmware or dns settings so while I had a Virgin engineer at my place sorting out some troubles with my phone I asked him to check the firmware of the Virgin-supplied router and ensure it was up to date. He noticed it was not up to date and forced a download of the latest firmware and restarted the router. Simple as that the problem has been solved. Interestingly, alike the post above, when I noticed I had the same problem when using Chrome I started to question if it was Safari's problem. My suggestion for you is to start with a hard reset/reboot of your router (unplug/turn off and then back on) and see if that fixes it. If not then try a firmware update. Good luck, I hope this helps.
