Car would crank but not start. Leaving it for a while (15-20 minutes) and restarting the car would result in a start but the "Check Engine" light would come on. The problem comes and goes and the Check Engine light turns off on its own after a while. Going to change crankshaft position sensor.

The engine would shut off when near idle. Sometime it would restart and sometime it wouldn't. Shop recommended replacing the crank shaft position sensor. Since that repair was completed the problem has not happened again.
