QUESTION: it shudders sometimes but it shuts down restarts and stalls again then other times its ok

Answer
Sue,
I would begin with adding by trying fuel treatment. Techron Black bottle at Autozone should be added to the fuel tank. Add the bottle, than fill the tank. It will take a little time for the cleaner to do its work. This may help remove any water in the system. If your are doing mostly in town traffic, I would take the vehicle out and run it at max posted speed for about 10 miles to  help burn of any carbon.
I would locate a reliable independent Mercedes mechanic and would I would also look at replacing the fuel filter, and  if the spark plugs have not been changed lately, that would be the next replacement.
Good Luck
Rob
