YES! This is exactly what I was experiencing. Well, to be exact, there were three or four different failure modes. What you described is one of them. Another was sometimes I close the lid to put it to sleep, and instead the fans would rev to 100% and sit there forever until I held the power button. I have the script running in a terminal window and haven't had a spontaneous poweroff for 2 weeks now.
