I agree with all the replies, if you eliminate the ground as a problem then it's gonna be a charging system issue.
I would do a voltage drop test from the Pos battery terminal to the grounding stud. It shouldn't be more than 0.5 volts. Then (if you can get to it) do the same test to back probe on the ECM grd pins (see your manual).
If your grounds are good then is very likely you have a charging issue.
