I've been experiencing the same issues. Unfortunately I have no cure, although it does turn back on again using the power button at the back.

Sounds like a hardware problem and a trip to the apple store. I would give apple a call first. Do you hear chimes during boot? You can hold D or alt-D during startup and try to run the apple hardware test.

I have reset SMC and did an extended hardware test last night which gave the all clear.

Are you running ML by chance? I've seen this as well on ML but it usually only lasts a few seconds for me.

Yes ML latest build. It's very random. I have checked temps of power supply etc and they seem ok, not too high. It basically loses connection on the ATV as the iMac and iTunes has shut down. I can straight away switch it back on and no crash reports are visible in the folders or console. It's very annoying when watching a movie as you can imagine.
I posted the content of the console here https://discussions.apple.com/message/23414478#23414478

I ended up taking my Mac to an Apple certified technician. They ended up needed to replace a power supply part...$300 repair bill. They said if that didn't work, they would have to order a different power supply part and the cost of that repair would be $1000! So, I guess make sure your stuff is backed up & if you are still under warranty - get it checked out!
