Have a 96 ZJ Inline 6. I have had a slow battery drain. But recently had both my battery and alternator tested as good. Any Ideas as to why the zj would not be able to hold idle causing it to die? Its fine under power but as soon as I take the foot of the gas the rpm's drop and engine dies. Thanks

Try a new battery, these jeeps will not run properly without a good battery.
Just do this test, pull a good battery from a diff vehicle and put it in the jeep, if it still does it, then its not the battery, if it runs fine, then you know it was the battery.

Most likely the battery, though it could be the alternator, if it isn't supplying sufficient voltage/amperage to the battery at idle. If my battery is a little weak (forgot to turn the lights off or something) it idles really slow until it gets charged back up.
Horsepower is how hard you want to hit the wall. Torque is how far you want to take the wall.
It could be a simple thing as a very dirty throttle body. My 5.2 wouldn't idle last year so I manually bumped up my idle and my fuel mileage wasn't very good either. I found out that my throttle body was caked with crap around the butterflies. I cleaned it up using a sensor safe intake cleaner and a soft brush. started the engine and sprayed the cleaner in the intake while feathering the throttle so that it wouldn't stall....the idle jumped up to 1700! I backed the idle screw back down to factory and everything is normal once more and got my fuel mileage back as well!
