Question type: Maintenance & Repair
My truck dies quickly . I need to everything that
needs to be checked because I am not convinced
it's the battery. We even removed the radio due to
this same issue, but now its still dieing faster. It
jumps off ,but doesn't stay charged for very long.

Have you checked the alternator? If it's dying while driving then clearly the alternator is not putting out proper voltage.

It doesn't die going down the road but just doesn't keep a charge.

Sounds like a parasitic draw , bad cell in the battery or the internal voltage regulator inside the alternator is not putting out or just bad connections that need to be cleaned. I would clean all connections positive and negative, Remove the battery and have it charged and checked. Remove the alternator and have it checked as well. If both check out do a parasitic draw test. Keep in mind a dead battery that is jumped started and not fully charged puts strain on the internal voltage regulator and can cause failure.
