i also found the dialogue about the ground wire on back of vehicle and mine was toast. Once I fixed it everything seemed to be good until that maiden voyage.

Intermittent electrical problems are fun for you and me!. Consider getting a meter directly or via a wire connected to the suspect point and back to a meter in the cab waiting to see what happens to voltage at the suspect point when you lose power.

On my 1999 Blazer ZR2 the nipple where you attach the fuel pressure gauge have outside treads just like a tire valve so is the adapter you put on this valve just like a tire valve adpter?

Thinking of the outside threads and that the adapter have to push down the small "pin" just like on a tire valve where you inflate air into the tire. This is a regular schrader valve or is it not?

It's not the same thread as a tire valve stem. The fitting for the fuel pressure service port comes already attached to the fuel pressure tester.
