I was out driving with no problems whatsoever, when I stopped to go to the store. I came out to go home and the car would crank and seemingly start, only to die before I could give any gas by the pedal. This happened 10X times, so I called MBZ roadside assistance. I took 10 min to get through, and before I spoke to a technician who was being paged from the local dealer, I went to try and start it one more time, and she started as if nothing happened before, It ran great all the way home (responded normally when doing an Italian tune up) etc. So what do I do now? Thoughts or suggestions?
