Engine quit just like shutting off of ignition switch. The problem turned out to be the fuel pump. While removing the fuel pump assembly noted that the attaching plug for the fuel pump had arced destroying the plug, and the wire supplying the power to the pump had all the insulation burned off and the wire was partially melted. This is a serious safety issue, as the arcing and melting of wires inside the fuel tank could cause and explosion if the fuel/air misture reached stoichiometric conditions.

Truck stalls, causing loss of power steering and brakes. Dealer has attempted to remedy defect on three separate occassions without success. Accidents avoided thus far, but next time, I may not be so fortunate. Please post these comments, to warn other consumers. GMC is denying responsibility, has flatly refused to repurchase the vehicle, and continues to attempt to repair the problem. I'm scared to death to drive this thing...me and my passengers(very often a troop of girl scouts) are in danger, and so is anyone who might be in front of me when this happens. I hope that no one dies as a result of this defect. Please help me.

Although their were no fatalities or injuries involved in reference to the master cylinder/ fuel pump, the lost of power brakes caused me to almost veer into a brick building. I hope the info provided will draw attention to the problems I've had since purchasing this vehicle.
