Sorry about leaving out that info. Engine is a 4 liter EFI crank sensor was
change about a year ago. The jeep starts right up all the time,but try and
go for a mile or two them shuts right off. Let it sit for awhile pump the
gas and it starts.I know you should not have to pump the gas on a EFI but
this works when you have set for awhile. Thanks Dean.

Ok.. about a mile or two is when the engine usually gets warmed up and
switches out of the open loop mode. That brings into play the O2 sensor
and Crankshaft Position Sensor (the one in the distributor).

If you were driving an old Chevy I'd suspect the gas tank breather
was clogged (eventually the pump pulls such a vacuum it starves
for fuel.)

Any buildup of oil in the distributor base? I was having rough idle
due to the bushing getting worn out.

How old is your O2 sensor and check the cable that runs up past the engine
block, it sometimes gets wedged in the clip and burns through.
