It sounds like your fuel sending unit is not working in connection to your ecm which is the BRAIN of your jeep. it is sending the wrong signals on how much fuel to squirt through to the fuel rail. check your fuel filters too and see if your fuel injectors are clogged or not ok?

i know on the 99 mountaineers with the 5.0 the way the fuel lines were routed from the factory, heat from the motor would vaporize the fuel in the lines when engine was cut off warm. It would turn quite a few times before starting after that happened. try turning your key on and off a couple of times before you actually try starting it and it should start quicker. I know this from experience.

Jeep starts sluggish and then wants to die


It is most likely from that actually. You may need to adjust the air / fuel mixture after modding the intake. Sounds like its getting too much air.

Engine dies, starts rough


Most large parts stores read codes free. Most common cause is crank sensor, but I'd have code checked before buying anything.

Jeep runs for a minute or two and losses it's spark for 45 min


Sounds like you need to Replace the Ignition Module.
It is a square box located on the side of your fender wall when you lift the hood approx 6 by 8 inch flat box shaped.
Go to auto store and they can show you a pic of it.
It Controls Spark plug Firing.
hope that helped

Check spark and fuel pressure. One is failing and must determine which to proceed further.
