I was driving down the road in my 02 GMC sierra and heard this knocking sound in the engine about 5 minuets later I lost all power in the vehicle, the check light comes on and about 3 seconds after that the whole vehicle shut off while driving. 4.8 ltr just over 60k on the truck. No prior problems and the knocking really didnt show up untill suddenly. The oil was fine and the oil pressure was normal
