MY 300E 2.6 is in the same boat. My mechanic (who also offers me advice for DYI, thank God) suggested Crank Position Sensor. I am trying this tonight - will advise if it works.

Car has new MAS, OVP is newer, tried a new coil...from other posts, I've seen numerous notes about the CPS. Here goes nothing.
