jeep starts fine than hesitates
Model: 1998 jeep grand cherokee
Engine Size: 4.0 liter fuel injected
Auto/Manual: auto
Mileage: 42,000
Jeep starts fine runs ok for about 1 minute than hesitates loses power like it is fuel starved if proded will keep driveing by stomping on accelerator but will run terribly for a few minutes than run ok. If motor is hot or cold at every startup!

RE: jeep starts fine than hesitates
Might be as simple as a clogged fuel filter and might be more serious. (fuel pump?)

I'd check for trouble codes even if the check engine light is not on. I'd also check the fuel pressure if nothing else comes up.

BTW, if you remove the fuel filter and can't blow through it that would certainly cause a problem like that and it could even be intermittent as you describe.
