I had the same problem on a millenia I used to have. I never found out what it was.

But It sound like an electronics problem, Im thinking a faulty crank position sensor or something

Fuel pump ECU is behind drivers side rear kick panel. I had the issue on my 92 Sc400 were when it was hot it would not start back up. To test, wait till the car is warm & when it doesn't start jump with a paper clip terminals E1 and TE1 in the diagnostic port in the engine bay, use this link.
