Have a 93 camary 4cyl, the motor shuts down when warmed up

Sounds like you are overheating the engine.

IAC or vacuum leaks

If I crank the motor while it is st ??????? Probably ignition module . When it shuts off check for spark .

It sounds like oil pressure switch is bad. You said you changed? To clarify, your oil pressure switch is also a safety item that shuts down ignition when oil pressure drops. Try an oil pressure gauge (hand held) to relieve your nerves about engine seizure. Make sure you're not getting to much fuel in engine also, that will dilute oil to a thin viscosity and show low oil press.

Hi there, have you checked the colour of the oil in the motor, if not clear or normal and have a milky look, it sounds like the head gasket is on the way, it will still drive but the symptoms sound like the head gasket, Check the oil. Hope this will be of some help to solve the problem

try unpluging your torque converter

4 or 6 cylinder? 4cyl. it is probably the t- belt slapping or one of the driven by belt items on the motor.

if the computer is located in the engine compartment it could be overheating. the solution to the computer overheating is a new computer. expensive. I have seen this happen on other vehicles as well.

Does it jump even when it's warmed up?
Change and/or check the oil ! ! ! !

change intake gaskets you will find it blown thats why your problem happens when your engine is warm the alum. intake warms up and expands opening the blown gasket
