    I just purchased a new 27" iMac (fully maxed out incl. SSD)

    I have used it for about an hour so far, and the only thing I've installed is firefox. Suddenly, it started going to sleep by it's self. I can wake it up and go right to the login screen, only to have it log out unexpectedly and repeatedly. I can be in firefox, safari, or with no applications open.

    I turned off auto log-out, and changed the energy settings to never sleep. I repaired disk permissions. The problem persists.

    I am now re-installing Mountain Lion. Any ideas?

    I found that eventually digging around in the /Library/Internet-plugins and removing some old files the logout loop stopped. Did this after booting in safe mode (hold shift down when booting).

    I also removed some LaunchDaemons which were old - but did both at the same time so I’m not sure exactly which change fixed it!

    This wouldn't apply to a new system with just Firefox installed.

    If it keeps happening after you reinstall OS X, you might have a hardware issue. Mind you, I'm sure what could be wrong with the symptoms you describe.
