Why did my Jetta stall?

My 2000 1.8L T Jetta recently stalled; on two prior instances the car had stalled but started back up immediately, so I passed it off as just listening to the radio with the car off too much. However now it is on the side of the road not starting. The battery is fine along with the spark plugs. There is plenty of gas, clean oil, and radiator fluid. Please help.

After sitting for several hours, the car started up first try with no problem. I proceeded to turn it off and start it again, and again it started on the first try.

Engine speed sensor (crankshaft position sensor) or ECM Relay. Either one will cause the engine to stall/quit, or NOT start when
the part is acting up.

The Crankshaft Sensor usually fails when the engine is hot and then
works again when the engine is cold. When it fails completely, it
won't work when cold either.

When the ECM relay fails, the "Check Engine Light" in the dash will
not come ON (when the key is in the ON position).

The next time the engine does not start, check to see if the "Check
Engine Light" is ON, when the KEY is in the ON position.
