Pontiac Grand Am Spark Problem

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?

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.
