Fuel pump seizes when in hot climates or when towing a trailer. Gm replaced the fuel pump last year and it appeared to solve the problem. But, the problem occurred again while pulling a trailer up and down a steep mountain pass resulting in a loss of brakes and steering when the engine stalled. This occurs when the fuel tank is at 1/4 full or less. The trailering fuel advance delivers fuel to the engine and if not needed then it is returned to the tank and recirculation. The fuel is warm when returned to the tank. The longer the engine runs the hotter the fuel becomes and when the fuel in the tank becomes hot enough the fuel pump, which is located in the fuel tank then seizes and the engine stalls. This is a major safety hazard, particularly when trailering in the mountains and the loss of brakes and steering occurs. The only solution when this occurs is to pull to the side of the road if possible, raise the hood and let the vehicle cool for 15-20 minutes and then start again. Or, find the nearest gas station and fill the tank with cool gasoline so the fuel pump no longer seizes. In the case of breaking down on the side of the road, this is another major safety hazard since this problem occurs both going up or down hills and there is a loss of steering and brakes. This means the vehicle is often in traffic and may result in an accident.
