I backed out of a parking place'put the vehicle in drive and it lunged forward as if the accelarator was pushed to the floor. I hit a light pole and the car stopped.

2003, Chevrolet Trailblazer. 4 speed automatic trans. 4 wheel drive. Standard length chasis. 6 cylinder engine. Problem experienced; upon acceleration onto the interstate highway, the engine lost power for appx. 5 seconds. The accelerator pedal remained depressed, the engine resumed acceleration after the time specified. Created much fear, since interstate traffic speed limit is 70 mph, and cars on the intersate came up onto the bumper very quickly. This is the only occurence to date. Also, gasoline filler neck too narrow, or vent hose constricted? frequent reflux of gasoline during the process of filling. Takes a considerable amount of time to "top the tank". So much time that, I have yet to been able to "top" the tank. Problem occurs at every pump, not indigenous to the gas pump, appears inherent to the vehicle.
