Im having a problem with my 1999 CLK320. Sometimes it will just stop out of nowhere even if my gas gauge sais half full or full. But whenever I put a gallon or 2 in, it starts right up. So at first I thought my gas gauge was broken. Until today it stopped on me, but I just put 10 gallons in it yesterday and I know for a fact I haven't driven more then 2 gallons worth of gas from then until now. But I filled my gas can up and went back to my car, put the gas in my car and it started right up again. Any ideas what could be the problem??
