Hi hammer124. Welcome to the forum. If possible, measure the battery voltage with a cheap digital voltmeter while the problem is occurring. It must be between 13.75 and 14.75 volts when the engine is running.
Check the small black wire from the battery negative cable where it bolts to the body. Be sure there is no break in that wire.
