My 93 grand am starts and runs for about 15 minutes then dies, won't start again. I have replaced the plugs and wires, battery, idle air sensor and the fuel pressure regulator and the fuel relay. I am getting 40 psi from the fuel pump. What could cause this?

40 is about the minimum. What is the pressure when it dies?

Sorry that was a misprint, the pressure is at 45 when starting and when it dies. It starts and runs for 15 minutes and gets to temp and dies, it cools off and starts and runs again for 15 minutes and dies again. Only paid 800 for this car and have about 300 in it.

Sounds like you know why they sold it now.

Find out if it has spark when it quits

Pull off a spark plug wire to see if there is any
