My wife has a 99 Ford Contour with 89000 miles on it. We are the orginial owners. 100K tune up was at 84000. Yesterday, while driving the car, the engine stops (Engine stops running). All electrical is working. Car restarts with no problem. Today, she is driving it and same problem. I told her to call the dealership tomorrow and to take it down. Any guess what could be wrong? I would assume that it's not the fuel filter since I would assume that it was replaced at the 100K tune up, if not, it was replaced at 73000. I'm thinking that the injectors could be clogging and they might need servicing. I have never had her injectors clean before. I figured, running good gas and putting in Chemtool in the gas tank every 5000 miles would keep them in shape.
