Recently, after several months of trouble-free ownership of a recently aquired 96 E300 Diesel, I experienced problems of the engine simply dying while running, and not wanting to restart. In all cases, I needed to give the car 5 or 10 minutes of rest before it would restart. The situation got so bad I was not comfortable driving family members, nor driving in heavy traffic on freeways - when it dies, steering is not assisted, although brakes will work for a while.
I tried numerous things, including the often suggested K40 relay inspect/resolder. I removed and polished every battery terminal, fuse, ground terminal, etc. All to no avail. A typical trip would be: Start normally and drive down to the store, run in, come back out, and no start - was too fast I guess. Wait a bit, and try again, and it would start.
Lakeside Mercedes Repair appears to have fixed this for $140 in parts and $73 in labor. I've been driving several days with no recurrence of the issue.
The culprit apparently was the "Crank Position Sensor" - which is mentioned almost as often as the "K40 relay" in discussions of die/no-start.
