CAR DIES AND WON'T START

1999 Oldsmobile Alero • 176,000 miles

If I drive the car for approx. 1 to 1.5 hours it will stall or if I shut the car off after driving for that time and try and start it 10 mins. Later it will start but run extremely rough misfire and shut off. I have to wait for about 45 mins. Until it cools down and it will start and run ok. Unemployed right now so I really hope you can help! Thanks. PS both situations same result have to wait to start. Could it be the PCM or a coolant temp sensor?

No to both.

Check fuel pressure. My money is a failed fuel pump
