Have 2001 Silverado 8.1 V8 Allison automatic. Reg Cab 2500HD. For about a year have a a intermittent problem with cranking but not starting and now dieing while driving. Vehicle will not start if parked on a step hill mostly with the front end up. vehicle has to be leveled off to start. Vehicle now also dies while under power. Engine stops running but all lights and radio work. Pull vehicle over wait a minute or 2 and you will here a clicking under the dash near your left foot. It may crank once or twice but will restart. When you see the read battery light come on if you floor it many times the engine will race and continue running. Codes found P0335, U1026, U1041. Dealer no help, Own service tech frustrated, any thoughts?
