If you mean it is going dead while sitting you might have a short or another issue drawing power from the battery. take your truck to your local battery warehouse/store the should have a meter thet will tell you if something is drawing on your system. It could be something simple, like maybe the mercury switch on your under hood light is bad and the light is not turning off thus running your battery dead over night.
