As I accelerate, my Blazer stumbles and pings as I am reaching second gear. Runs great any other time except on hard acceleration. It stumbles bad enough to buck hard and leave me feeling it could stall.

Could need plugs and wires especially if they have never been replaced, another thing that is cheap and pretty easy is to replace the fuel filter. Not sure if that would cause your problems or not but is a good idea to do yearly.
