My car will suddenly quit running, the dash lights go out, no power at all, while driving . I can be driving down the Interstate with my foot on the accelerator and it will cut off, or taking offfrom a dead stop, coasting, changing gears, or at any time and the car will suddinly just quit running. I have no power steering or control of the car. I can put the car in neutral and start, or stop fully and put it in park and start it.The mechanic has connected it to a computer while running and cannot get it to simulate the problem. Do you have a diagnosis?

It is possible that you have a failing ground cable from the alternator mounting bolt to the frame rail. This may be influenced at times by engine motion, and possibly a broken front engine mount allowing to lift and stress the cable. Or the cable could be loose. It is viewed at the right front corner of the engine compartment.
