So my 96' GMC K1500 Extended Cab is in a funk. I hit a decent sized pothole and since then my truck has shut off a couple times while driving, it does return within a 1/2 second so I am guessing it is a ground.
Examples: When I am going on a left hand turn, at a high rate of speed and hit a small crack in the road and my right rear tire loses contact with the ground it seems to happen. I pulled into the driveway this evening a few mins ago and it shut off, about went into the ditch. lol

So I have changed my connections to the battery, and it is a side-mount so I also changed the through-bolts, tightened the bracket that holds the battery down. But that has not made any difference.. ugh
Just not wanting to get stuck in the middle of no where, it did start back up in the driveway and my amp's are over 14 which is decent. When I turn the truck back on the amps are still above 14.

So that eliminates the altenator, and battery. It seems like it is located on the back rear-right axel because when it does shut off, the first thing I noticed the first time was the Brake Light, then the ABS light. So could this be something with the brakes?? I wouldn't think so, but it seems it is located somewhere around the rear axel..

Any info will be greatly appreciated, snows falling some so I need to get this fixed before I get stranded in 20* weather...
