RUNS GREAT FOR 15 MINUTES AND DIES

1998 Dodge Avenger

Engine Performance problem
1998 Dodge Avenger 6 cyl Front Wheel Drive Automatic 130000 miles

I have had the fuel pump changed and it still runs for 15 minutes and dies and will crank but not start for hours at least 5 or 6 hours and then starts back fine and runs for 15 minutes again. What exactly could be wrong with it. It drives fine when it runs but dies after 15 minutes. Never had anything else wrong with it ever until this about a month ago.

Next time it dies out don't wait for nothing do below immediately to determine if its fuel or spark problem

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
