I suddenly had this same problem. After fiddling around with lots of things the past 2 hours I got it to work. Try this and see if it helps you.
Go to Preferences => Advanced, then click "reset cache". Then try syncing. I had also restarted my phone and quit and restarted iTunes so you may want to try that too.
I have to take that back. It finally LOOKED like it was syncing, but I still ended up with no podcasts after the sync was finished. :-(
