The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Car starts up every morning however when I shut it down to go into store, gym, restaurants etc. many times (but not every) it won't start again unless I wait 20 min. or more (sometimes an hour).
Any ideas why?
Takes alot of fun out of driving the vehicle not sure if I go out to dinner if it will be a hassle to get it going again.
Starts and runs fine for about 10 mins. Afterward - begins to hesitate and idles roughly. After cutoff - restarting results in choking, coughing, sputtering engine. Sometimes doesn't restart. And stalls at idle when this condition occurs.
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.
after parking and turning off engine, I could not turn the car back on. The car started after cooking off. During drive to mechanic, the car stalled on the road. Diagnosis of crankshaft sensor. $600 repair. Saw a fix on youtube that takes a total of 20 minutes with one tool.
Just clean drove around and stop the car in front of the garage and have to push the car into the garage...She cranks but no sign of starting...
Engine would die, then restart after cooling for 15 minutes. Sensor was replaced for $285 and all is well.
Crankshaft position sensor failed resulting in no engine ignition and a flatbed tow to the dealer. evidently this is a fairly common occurence due to age of vehicle.
same - cranks - diesels - wont start
Driving car on highway at 60 mph. Car stalled out. Crank shaft sensor needed to be replaced.
Didn't restart for 10 mins....then 30 minutes...until no start at all.
Seems like the same problem. Engine cranks, but won't start. Intermittent. When the car starts, it runs fine. Took it to my repair guy today and he said "common problem, crankshaft position sensor." Should be repaired on Monday (today is Friday).
The car stalled and check engine light came on. Had towed to mechanic and he replaced crankshaft position sensor, no problems since.
Starts cold and runs fine. After shutting down after a drive, car cranks and won't start.
literally drove the car and parked in municipal parking garage. when I went to get the car out (2 hours later), car wouldn't start and had to have it towed to dealer for repair. luckily I had an extended warranty.
Engine not starting when hot. When engine cooled it started fine..
Recently my car wouldn't start when we were leaving a friends place. 10 min later it started. Yesterday it stalled at a light. Didn't start for 1 hr. Took it to a dealer: Close to $600 to fix. (200 part and rest for labor and 40 tax)..
I will never buy Mercedes again. For the price it is poor value. Car seems to be made to purposely have certain problems and they tend to force you to go to the dealer for fixing. My private mechanic said parts and labor should have been $300. (unfortunately he couldn't fix it yesterday for me)
Car driving "rough"....almost like coughing at speeds of 40, engine light on, took to dealer...$600 to fix the crankshaft sensor. :(
