99 Jeep Wrangler Wont Stay Running

I bought a 99 wrangler, my guess from the owners story is someone had it in a field playing and it quit running,They put a new fuel pump drove it a mile or so then it died in there driveway they never finished working on it... has sat from a year to a year and half no with no gas lid.

I have so far, Had to Replace :

Battery
Alternator
plugs

Then it fired right up, when after it got warm it would die, now when it starts if you touch the gas it dies, if you let it idle it slowly dies then works itsself to not wanna start.

Fuel Pump Primes and sounds to be working
Got new Coil didnt make it run better
jeep doesnt use cam sensor but
tried new crank sensor didnt run better,
added heat water removing gas treatment added some fresh gas and octant boost
didnt help make it run better, checked pcm connections and
all fuses im lost now...... any ideas?

Yes your TJ does use a camshaft position sensor, it is inside the distributor underneath the plastic shield underneath the distributor's rotor.

Did you check the air flow sensor? Or the throttle position sensor?
