Crankshaft position sensor

Hello, stop and don't jump to the conclusion about a "crankshaft position sensor" issue, first off. If your engine stalled while driving, you'll have to first find out if you lost overall electrical power (such as a battery that could not sustain charge due to a fault with it or the alternator and charging system), or a mechanical issue (such as fuel delivery, ignition spark, engine timing, air intake, or internal mechanical engine concerns). Hands on testing is needed; it's too wide open from the information you have provided thus far to know what is going on any further without testing.
