95 S10 4x4 4.3L ECM Bat Fuse Blows

I have a 95 S10 4x4 4.3L, that will blow the ECM bat fuse only when the truck is in gear and I give it to much gas (goose it a little). When its out of gear I can goose the heck out of it and rev the engine to high rpm's and the fuse won't blow. I also had a repair shop run a diagnostic on it and it shows everything is fine. I've changed the fuel pump wiring harness and ECM. Any thoughts about what it could be.

Check for a pinched wire that is grounded when the engine torques over. That will blow a fuse.
