Occasionally, much too often for my tastes, after driving around I come to a stop and the engine quits for no apparent reason. I restarts immediately, so I have not been stuck, yet. I have replaced the crank and cam sensors and still no joy. My next step is to check the relays in the RCM for arcing. Anywhere else I should look? OBD scanner shows no faults at all. '05 base Coupe, 6 speed manual.

Thanks in advance.
