Need diagnosis on a problem.

About a week ago while driving my girl's car it just shut down and would not start back up at all. So I took it to the toyota dealer and they said all it was was that some connector in the harness, not sure what harness they talking about, was dirty so they cleaned it up and everything was fine. When we got back the car we noticed that i had somewhat a loss of power. When taking off from a standstill it like hesitates (no jerking), then takes off fine. Now yesterday same thing happened it shu down and would not start. We took it back to the dealer and they said after a while when they went to put the car in the yard it started up fine. They took down the throttle body and cleaned it and said they saw nothing else wrong, but we still have the loss of power and it feels as if it would shut down again. Any idea as to what it might be? Thanks

I have no idea which motor you have but it sounds like the coil may be going. The symptom of dying when warm and starting after it cools, has fooled many a tech. Next time it dies, check to see if you have lost the spark.

The car is a '92 Toyota Camry 5SFE motor.
