2002 Dodge Ram won’t idle.

5.9L v8 weekend truck won’t start. Battery has charge but I just get aggressive starter clicking when I turn the key. When I jump it the engine will fire and I can stay on the gas and the engine will run. However it will not idle and will die about as fast as you remove your foot from the pedal. I would assume that it’s probably a air flow issue (maybe a sensor) but why the difference in performance when I have the battery jumped off? Would love a few pointers since I’ll be under a heavy workload this week and will have minimal time to address it if I get any time off this weekend.
