Have to jump to start alternator. Checked out okay, new battery. After letting in run for a while drove approximately five miles shut truck off would not turn over. The amp gauge does not show it charging unless over 2000 rpm.

This sounds like a drained battery again but we need to find out how you tested it that it passed.

Here are a few guides that will help with this testing that we need to do to the alternator and battery:

I suspect the alternator has failed and when you are running it, it runs off the battery only and eventually drains the battery.

I attached the process below on how to replace the alternator as I suspect this is the issue.

Let us know what you find and we can go from there.

Thanks
