2003 Ford Taurus electrical system problems

On february 5, 2010 my 2003 ford taurus caught fire at 1:00 p.m. Parked under our car porch and there was no one in the car and no one had driven the car for 5 hours on saturday morning. The shreveport fire department was call to keep the house from burning down with the car. The city fire marshall said the fire was caused by the cruise control switch. I told him no one uses the cruise control in that car because we just go in town and there is a red light at every corner.

Tl*the contact owns a 2003 ford taurus. While driving 70 MPH, the vehicle shut off in the middle of the highway. All of the instrument panel lights illuminated. The vehicle was able to be restarted, but then shut off again. The contact stated that the speedometer also displayed the incorrect speed. The dealer acknowledged the failures, but the diagnostic indicated that nothing was wrong with the vehicle. The vehicle is currently at the dealer. The current mileage was 122,000 and failure mileage was 100,000.
