CLK500 cutting out at stop
Twice its gone completely dead at a red light and stop sign. I was sitting there and all of a sudden the dash board lite up as if it were in position 2 in the ignition. On both occasions its started right back up, but this second time it shows check engine light. Any ideas on what would cause this. I did a search but to no avail. Could it be the CPS (crank position sensor) AGAIN! Its been replaced I'm guessing because I remember seeing it in the car fax, plus we have the new style silver/chrome keys

If the MIL is illuminated, get your codes read. It could be the CPS, but usually it won't restart until it cools down. Also, CPS doesn't usually throw a DTC. Was it a clean shutdown, or did it sputter? If it sputtered, it could be the fuel pump, which also may not throw a DTC, unless you get a misfire or lean mixture during the lack of fuel.

it was a clean shut down on both occasions. The check engine didnt show until the second shutdown which was a week or two from the 1st shutdown. The second time it took a few tries to get it restarted. Its at the dealer now. I'll find out more later today and I'll post the results of the findings.
