Hello: Since I've owned my 240 it has cut off while driving, I don't know if this is the same as stalling, only four times. I read some other posts, but I am not sure what to do. The first time it was cold and I was driving as if it wasn't. When it cut off, I knew what it was and then it restarted right away and I took it slower. The next time was about two months latter. I was driving on a warm day; I had been driving for 30 minutes. I was approaching a red light and all the service panel light came on and the car stopped running. I restarted it and it turned over right away. Time number three and four were yesterday, I was driving for about 10 minutes. The temp indicator had me well with in the normal range. I have a 1/2 tank of gas. The car shut of while driving I may have been accelerating slightly. Scared, I drove to a gas station. I got gas, I actually purchased high-octane gas this time, and I restarted it. And it cut right off. Then, waited a minute, cut the radio off, which controls an amp installed a month ago. I figured anything could help. The car started. The engine sounded normal.

In August I did the dealers 150K service new Timing belt, plugs, fluids, filters (I think the fuel Filter), oil/filter change, a drained transmission, and more stuff I can't remember now. In November replaced to O2 sensor. Starter in December (Same month as the second cut off).


I am not sure where to start. Could this be a fuse or a relay? Or am I looking at spending a huge amount of money?
