Any number of things could be doing this. From a simple bad battery ground
to sensor failures.
Pull the engine codes and let us know, ok.

By the way, pumping the gas or "goosing it" only works for carbureted
vehicles, doesn't do squat for fuel injected ones.

Re: Jeep Engine Stalls Just After Startup
I believe that failure is in the Fuel Pressure Regulator the six
cylinder is pictured at:
http://members.***.net/wilsond/Fixes....html#fuelrail If this
happen when it hasn't been sitting then it could be the Crankcase
Position Sensor, talked about in this old Cherokee site:

Re: Jeep Engine Stalls Just After Startup
Sounds like your not getting fuel. The ecm primes the fuel system when you
first turn the key on (runs the pump for 2 sec) then shuts off. once the
engine starts and is running it turns the pump on continously once it "sees"
oil pressure, and various other signal from other sensors. the engine can
run for a few seconds on this initial "prime", then shut off.
one problem i have come across on the same vehicle as yours was a faulty
ignition switch not supplying power to the main relay causing the vehicle to
stall after start-up.
are all of the guages/lights on the dash functioning when it stalls? as
suggested , check ecm codes. what you might try is to get somone else to try
starting it
while listening for the fuel pump. you can do this by putting your ear near
the fuel tank and listening for a hissing/humming sound or by removing the
fuel filler cap and listening there. see what happens first, either the
engine stalls and the pump runs for a second after or the pump stops and the
engine stalls.
