Put a new alternator, new battery, new fusible link, and can jump start the truck and it runs. As long as it's linked to the jump vehicle, the radio and a/c works.

I let it idle for an hour, then went out and turned on the a/c and the truck stalled out again. Won't start unless I jump it...again.

Guidance?
