“The contact owns a 1986 Ford Mustang. The contact stated that while driving at approximately 20 MPH, the vehicle stalled and he was able to continue driving in second gear. The vehicle then lost motive power and failed to restart. No warning lights were illuminated. The vehicle was then towed to an independent mechanic where it was diagnosed that due to an electrical failure, the spark plugs, distributor cap, ignition wires, and the ignition control module needed to be replaced. The vehicle was repaired; however, the failure reoccurred. …”
