I know mine has shut off like that too....sometimes in the middle of a burn or a heavy conversion (grrrrr)...

I noticed the fan is on the bottom and the coffee table I keep it on was really warm. I added some rubber feet to the bottom which keeps it up just another half inch or so and found it gives much better ventilation and doesn't do that much anymore.

Also if I am going to do something intensive (like a conversion in tmpgenc), I'll sorta leave the spot where the fan is to hang a little off the edge of the coffee table so the air is definately getting in there.

Worth a shot
