I get a miss or feeling as if it shuts off or goes into neutral at any speed as I'm coming off the side of torque. I have replaced wiring harness, TPS, main computer, crank sensor and reluctor, cam shaft sensor, plugs, wires, distributer, injector spider, mass air flow sensor, Ox Sensor. Chevy Dealer mechs have no clue and after 92 hours of labor still no answer for the problem.
There's no certain shift point or speed that it does this. I can stomp on the gas and stay in it but no matter what speed I decide to come off the torque it will bang hard as if it went into neutral. It's hard on the universal joints for sure. I can even brake torque it up to 1500 rpms and slowly come off the torque side and then bang it does it again just for that split second and then pics right back up as if the firing is interupted or goes to neutral. Please help I'm lost.

Just a wild shot, but try the ignition coil and or module if it has one. I had a 96 Silverado and sometimes it would just DIE. There was a single wire coming from the coil that became frayed, so if I turned hard or hit a bump, it would interrupt a signal to the coil. Just replaced the coils on an 02 camaro v6 at only 81K miles, they were all bad.
