My car drives for about twenty minutes straight then dies on me. If I let it sit for about twenty minutes it will start right back up and drive for another twenty minutes before it dies again. What is the problem with this car. I was told the fuel filter so I replaced it and it still dies on me. Any information that you could provide would be greatly appreciated. Thank you for your time. I was also told it could be the cold start sensor.

Next time this happens don't wait for nothing, do below immediately to determine whether it's fuel or spark related problem.

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 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.
