Could something be physically moving and shorting out the power wire under hard acceleration?

My car is a 73 Corvette with 2002 Ls1 from a 2002 WS6 Trams Am. I have a 10 amp fuse and the ecm and fuel pump share the same fuse. Going to try a 15 amp fuse.I shook all the harness and nothing happened. Going to find a good road and try it out tomorrow. Will update tomorrow.

I would put the ECM and pump on separate fuses. The way it is now you don't know which one could be blowing the fuse.

I was wrong about fuses. There are 3 fuses 1 pcm ingnition 2 fuel pump 3 pcm battery. It runs fine till you stomp on the gas peddle. Do you think the tps sensor could be bad ? Thanks Charlie.

I found the problem.A terminal was sticking out of the plastic connector on the mass air flow sensor.It was grounding out on full throttle. Runs fine now no blown fuse.
