I had a defective ECM once. Car would start fine in the morning or when I parked under shade. But if I tried to start car after a long drive or when engine was hot it wouldn't go. It just cranked. I switched out the ECM the problem was gone.
I would test it out before searching for a new ECM. See if cooler engine would solve your problem.

as long as the motor is cooled down fully it will start, and run fine, no issue's. looking for a compatible computer to borrow to see if that is it. i'm working on this car for a friend, his is a 93, my computer is totally different.
