Tighten and clean all battery connections. Test output voltage of your alternator. It should be putting out 14.5 or so volts. If it's not then it's probably going to need to be replaced.

Also what year model is your truck? If older than about 2002 or so might want to tighten and clean the negative battery cable on the frame and motor. If they loose or dirty they can cause the same issue.

Beyond cleaning the battery cable connections, and replacing the battery cables, your alternator might be going bad.
