I have a 1998 E320 that just recently began acting up. When I start the vehicle after a period of rest, the engine starts right up, then dies immediately. I restart the motor and it runs fine until I shut it down and let it sit for a couple of hours, after sitting a few hours, same thing, upon initial start up it dies immediately, then restarts and runs fine. I have no fault codes indicated. I am thinking it may be the Crank Sensor. I had to replace it about 2 years ago, but at that time it would shut down without warning while driving down the road.
Any ideas? I would appreciate any help.

Regards,
Ray
