Vsa Warning Light On problems of the 2009 Chevrolet Silverado 1500

I was at 60 to 65 mph on an interstate and the truck powered the motor down. The electronic stability control module light came on and the service engine light. I was able to get off at the last safe exit for quite a way. Onstar recommended not driving it to the dealer. The dealer did the diagnostic and at 28000 miles told me it was the throttle body assembly. It took 5 days to get a "new" one. ( aprox 1/26/11) on aprox 12/15/11 an almost identical thing happened, mileage 50000. Out of warranty I took it to a local shop. Their computer test concluded a throttle body assembly malfunction. $450. 00 to repair. Call the dealer " no that is under warranty" dealer concluded that it "just needed cleaned". Prior to service (I rely on this truck for work, I can not get a ride, I can not ride a bus) I was able to "reset " the stabilitrack ( the button would not turn it off) by pulling 4 fuses under the hood fuse block. But boy when it had enough the truck would power the motor down and within 15 seconds the truck would die right where it was. 5 mph, or 15 mph no power nothing, brakes ,steering gone. ## VIN passed ## Chevrolet k1500 2009 ##.
