Mercedes-Benz SL500 Engine Performance Problems Due to Crankshaft Position Sensor Failure

Problem began by exhibiting the "crank but no start" behavior. Was told that perhaps the computer chip in the key was not transmitting correct data and to get a new key. Next it stalled at low speed (approaching a stop sign), and would not restart until approximately and hour had passed. Then stalled again at low speed in a parking lot, re-started 15 minutes later, and then stalled for the last time in the same parking lot. Called for a tow and left it. The car started fine the following morning so was able to get it onto the tow truck and get it to the shop. The crank shaft position sensor was replaced, and so far no more problems.

Engine would die, then restart after cooling for 15 minutes. Sensor was replaced for $285 and all is well.

I had it replaced.

Car would not start, ignition turned over but would not start. Started occurring occasionally with increased frequency until finally would not start at all. Mechanic shop replaced crankshaft sensor and all is fine now.

ENGINE WILL STALL AT A RED LIGHT AND NOT RESTART FOR 5-15MINUTES
