Default 1994 Cheyenne v6 will shut down intermittently, no codes.

I am working on a fix for a 1994 Chevy Cheyenne with a problem. 1st problem, there is something "hot" going on with the wiring, as the battery will draw fire when it is plugged back in. I suspect that whatever it is will draw the battery down so that it will not start and run.
Next is that it will start and run, but will quit with no warning, and will not start again until it sits for awhile. I have changed the fuel pump, the fuel filter, the fuel filter relay, all to no avail.
Any suggestions, and where can I find an accurate wiring diagram for this truck?

Do you have a check engine light?
