Could be your starter is binding up

It may be time for a new one if the batteries and alternator check out good

There are no codes that appear outside of voltage related errors. This is leading me to believe it's something power related? The guy at the auto parts store mentioned starter relay? I have no issues starting the truck and jumping ... It's just when it's standalone not connected to a jump box
