"Crank no Start" Due to Failed Crankshaft Position Sensor on Mercedes-Benz CLK430

The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

still working to replace crank case position sensor, bolt holding sensor is under sensor, with heat shield making difficult to remove, car runs like new when it does start, hope I can get that sensor out.
My vehicle would start and was able to drive about 1/2 mile before I lost engine power. The vehicle would not start until the engine cooled. I paid $338.00 to have a diagnosis on the vehicle and replacing the crankshaft position sensor.
Vehicle occasionally would not start and sometimes would shut down while driving. Replaced crankshaft position sensor.
Jumped in my car and tried to start it but it would not start. I tried again after a few minutes and it was able to start. Mechanic confirmed the problem at the repair shop.
Car chokes in traffic but after cooling down it starts rough a bit
how do I get the connector off if the end (part you bend down) broke off? thank you
Had this problem at 80,000 and 201,000 and now again at 215,000. Engine cranks but won't start, especially when warm. Starts after a few attempts. The problem is intermittent but increases in frequency over a couple months until it's constant, and at that point the car periodically stalls. Also, occasionally rides rough with what feels like a loss of power. Replaced the crankshaft position sensor both times previous and it fixed the problem.
