Check all of your ground wires. It could be that you have one loose.

I had a similar issue with my old tahoe. Turned out to be the negative terminal on my battery.

Nothing stays tight forever.

Checked wires all seem tight clean terminals

You either have dirty, loose or damaged wire somewhere or a really funky battery or alternator internal issue.

the stud on the back of my alternator is loose on my 97 tahoe the voltage was jumping all around and the battery light was coming on. that is where i found the problem
