Truck has a new battery and "usually" starts right up but by the time I'm at the bottom of my driveway it dies. Not just engine ... FULL engine/electrical failure. Pop the hood and "wiggle" the engine bay fuse box and power comes back, truck starts right up, drives a short distance and it all starts over.

Ideas? (no fuses were loose, I did at least check that)

Thanks in advance for any replies.

 

I would start with a ground issue. Take a look at the ground connections starting around the fuse panel. Also, check inside the battery terminal crimps - corrosion can hide inside them.
