Car runs great. Engine suddenly cuts out. All warning light bank comes on.. Turn key off, restarts immediately and runs as if nothing is wrong 'till the next time. Maybe in an hour, maybe in a day, maybe longer. Porsche dealer had car for three months looking for problem. Simply determined it was electrical. Finally decided it was a faulty battery and installed a new one. Declared problem solved. Ran fine for about 50 miles before cutting out again. Car otherwise in perfect condition. Mechanics at a loss. Cut-outs occur about every 20-25 miles, and at times when idling. Dash llights do not go off when engine dies, so presumably the electrical system did not shut down.

Hi, I have a friend with the same year Boxster, and about the same mileage doing exactly the same thing as yours. Did you ever find a solution to this problem? Any help would be greatly appreciated! Thanks, Dave daves944 at yahoo dot ca
