I have a '98 E320 with 53,000 miles. On the way to work this morning the car shut off at 60MPH. I coasted to a stop on the side of the highway. Once stopped I tried to restart the engine with no success. After several attempts to start, it finally started with the check engine electronics and check engine light warning displayed. I drove directly to MB dealership to have them check it out. It will be several hours to find out what the problem is as I did not have an appointment. The car ran well during the 20 mile trip to the dealer. Any suggestions on what may have caused this?
Yesterday after a 45 mile trip the car took several attempts to start but finally did start but no warnings were or lights displayed.
Any suggestions?
