C230 Stalling Problem
 

Hi! My 1998 C230 will occassionally stall at a stop light after driving it 1-5 miles or not start after a short park. It turnsover but will not start. Let it sit for about 10-15 mins. and it starts. It will than run good for a number of trips and than repeat the stall. I replaced the fuel filter relay and it didn't fix the probem. Any ideas? Thanks! Geo.

crankshaft position sensor?

how much are those? and are they easy to change on you're own?
