I have a 2003 saab 9-5. When driving my car after about 2-3 miles it will shut off like it runs out of gas. and will not start. Once the car sits for a couple hours it will start back up and do the samething. i recelntly had the fuel pump, lines, and filter replaced. I also bought a new battery and had the aternator cheaked. My car is well maintained and runs perfect while it stays started! PLEASE HELP bc im out of ideas! A friend said it might be my Crankshaft Position Sensor?
