95' cutlass sup, Idles rough and dies....
 

I have a 1995 Olds cutlass supreme, When I start my car it runs for awhile but once it gets warm it starts to idle rough and then eventually dies. When I go to turn it over again it wants to start but wont. If I leave the car for a few hours and come back the car will start right up but eventually does the same thing. I've changed my fuel filter, my coils, the plate under the coils, my thermostat and i'm lost as to what could be the problem. I had a diagnostic check on my car last year and no codes came up but then again 95 was the transition year from OBD1-OBD2 so even if my check engine light was on it still would be difficult to pull any codes. Any suggestions? :confused:
