So made complaint, after a day of testing I was issued with a replacement Smart Key, its better, but occassionally still gives the same problem, although engine will now keep running on the second start.
My old key I repaired , its OK, no problems.

Aha! Thank you for posting! This is exactly what's happening to my daughter's car and I was about to embark on a wild goose chase thru the car.
Car is 1999 C280 and purchased only about a year ago with one key. Car driven lightly but one day the key would not turn in the ignition. Tried unhooking and hooking up battery. Tow truck came and tried jumping. Nothing could get the key to turn. Tow to the dealer where a new key was ordered. When the car started with the new key, further diagnosis was ended.
Now the car will do as you described. Car will fire then die at random. Second or third start would be fine and the car would drive normally.
I was about to start going thru the car but your post has saved me the trouble. It never occurred to me that it might be the key.
How did you go about repairing your key?
Thanks,
