What causes a car to turn off by itself?

I was driving to work, and my car shut off all by itself! Luckily I could pull to the side of the road and get it restarted, but I don’t want it to happen again. What would cause a car to turn off by itself?

  • Faulty crankshaft position sensor
  • Damaged or faulty fuel pump
  • Clogged fuel filter
  • Bad alternator
  • Faulty ignition switch
  • Malfunctioning sensors
