While passing a vehicle I lost all electrical power which in turn caused the vehicle to lose power. This same thing has happened several times at low speeds. I have the vehicle scheduled for July 2 to get looked at. The engined revved extremly high and it seemed like the transmission went into neutral. It then restarted. I had to roll the driver's window down and got a stabili Trak light that came on after the incident.
