When I drive for about 40 minutes, the car will shut off and will not start untill it sits about 10 minutes, especially when you run the ac. It only happens when the weather is hot. I have changed the fuel pump, fuel filter, ignition module, coil, crankshaft sensor, rotor cap and distributor cap. When the car stalls it does not put out any code, plus the engine compartment is hot.

Check the fuel pressure when this happens and make sure you have the proper residual pressure. A bad fuel pressure regulator will cause this problem. It is actually vapor lock in the rail because of the lack of pressure in the line.
