2005 Ford F-250 SD electrical system problems

I was heading down my street in my neighborhood and just before the street bends to the left my truck stalled and I lost my power brakes and power steering. Doing the best I could I turned the wheel just enough to avoid the car parked on the side of the street then I proceeded to run through my neighbor's wrought iron gate and plaster coming to rest on the hill in his front yard. After assessing the damage, I tried to start my truck to see if I could move it. It started and I moved it to my driveway.

Tl*the contact owns a 2005 ford f-250 superduty. While driving 55 MPH, the vehicle stalled in the middle of the road and would not restart. The vehicle was towed to the contact's residence. The engine completely shut off, but the batteries and other lights in the vehicle functioned normally. There were no warning indicators illuminated prior to the failure. The vehicle is still at the contact's residence awaiting repair from the dealer.
