If I let it warm up to operating temperature and then put the relay and switch back on then it works fine. As soon as it cools down, back to shutting off after two to five seconds.
My next, and scary thought, is the computer itself. What are the chances of that?

Yes and no on the computer.
Pull it down and give it the old tap twist it test.
Good luck
