2000 Grand Prix GT stalls when idling more than 2 mins. No check engine light. Starts right back up. Crank shaft position sensor? Car runs well otherwise. Lots of power, starts right up. Just stalls randomly when driving a lot and when idling.

Try cleaning the throtle plate with choke cleaner on both sides as well as the idle air contol valve hole. Car will start hard after doing this and make sure duct work is hooked up before starting.
