Sounds like the truck is loosing voltage. Have the battery charged and tested, inspect all battery connections for corrosion, clean them and make sure they are tight. Check and clean the battery connection at the starter. Also have the alternator tested at a local O'reilly Auto Parts store or similar. This is a free service.
