Mac Book Air restarting when asleep since installed 10.10

My MacBook Air restarts when asleep. My Air is a mid-2012 model running MAC OSX 10.10.1 with 8 GB of RAM, i7 chip and 256 GB SSD. This problem started when I upgraded to 10.10. I have reinstalled OSX but it has made no difference. When the computer is left for an hour or so, it restarts and I am presented with a new startup login screen when I seek to use it again. I have run Disk Utility (repair disk and permissions) as well as Tech Tool edisk to rebuild the volume. Nothing has alleviated the problem. Any suggestions on how to correct this?

MacBook Air, OS X Yosemite (10.10.1), 13"

Have you actually heard it restart when asleep? Start up chime etc?

Did you have to log in after sleep before?

Go to System Preferences> Security and Privacy Select the General tab. Uncheck the Require password after sleep.

Hope this helps.

I do have the box checked to log in after sleep. But the computer is shutting down all open programs and restarting. If I have a program open that requires a Save before shutting a file, that halts the process and when I go back to the computer it has the Save dialogue up. If no file needs to be saved, all programs are shut down and the computer shows a full login screen (user name plus password), instead of just the password screen as when waking from sleep. Got me beat!

I think I have been able to replicate this and looks like you are not going to sleep but being logged out before sleep. Go to System Preferences>Security and Privacy>General>Advanced its the log out time set to greater than the sleep time in your Energy Saver Preferences.

I have been having this problem for 2-3 months. I see the problem was solved for you, but for me the above didn't help. But a few days ago I realized that I had turned 'Guest User' (Login options) on right about the time the problem started happening. I turned that back off and the problem has gone away.
