Do you have a check engine light on and what are the codes if any? Your symptoms describe 4 things I have seen go bad on this car. A bad cat converter can cause this. A bas fuel pressure regulator can cause this. Pull vacum hose of fuel pressure regulator and inspect for liquid fuel. If there is any than the part needs replaced. A bad mas air flow sensor can also create this problem. A weak fuel pump can also cause this.

It sounds like your ECU is failing when it sits in the heat for a while. It's probably due to a faulty solder joint, and the heat may cause the board to warp momentarily, causing the engine to shut off. After the board cools down, you can start the vehicle again. You can test this by using a large fan, sealed ice pack, or similar to cool the ECU, while running the vehicle. If it sits and runs fine for longer than usual, replace the ECU. If it still shuts off, you may have a sensor that is failing when it gets hot, which will probably cut the spark, causing it to not start until the sensor resets. This is more complicated to track down because each sensor must be monitored while running the vehicle to know which on is failing when the engine shuts off.

Testimonial: "Thank you. Found a leaking fuel pressure regulator leaking into the vacuum line. Replaced it, and engine runs great, idles smooth, but now it will not start when engine is cold. Can you help with this?"
