Hi Chuck,
Strike the above, i was answering the wrong question!
Powering-up and shutting down, or lamp shutting off, is usually brought on by a problem with air intake. Clean all external vents/filters and open up the projector an dust internally if your can.

Hi Chuck,
Some infocus models were fitted with a weak internal fuse. You can replace it yourself for pennys. If your good with disassembly, its worth a shot.
