Need to keep air moving over the pump to cool it. That's why most FI f'pumps are in the gas tank.

That is my next move since when this happens the pump is hot after just a few minutes of running.

I moved the fuel pump to the back of the jeep last night and that seems to have solved the fuel delivery problem. No my ignition system id cutting out again ugh! it's looking to be the distributor or coil since they were reused after the rebuild. I took the ignition module and had it tested and it was good.

Run a 'jumper' wire from the POS(+)side of the battery, to the POS(+) side of the coil.
Start eng and drive around to see if it dies.
If it runs OK, you may have an issue with your ign switch. This 'jumper' bypasses the ign switch.
You'll need to 'pull' the wire to 'kill' the engine.

Don't drive it to long because the increase in current without the ballast wire can over heat the output transistor in the ICM.

Is the tach doing it freaky thing also?

John, that is one reason I want him to 'hot-wire' the ign. To see if the ICM goes TU when hot.
Also to rule out ign switch issues.
Other than a wiring issue. It's a toss up now.......

Ah, I thought you just wanted to test the ign switch circuit.

Other than pulling on wires and plugs, I wonder if there is any other test on corroded/broken wires...

Just hope'n the plug on the steering column isn't broken from age/heat etc. and that is NOT the intermittent we are seeing.

Ok I'm not with the jeep at the moment but my mechanic and son are. They have tried a spare coil and distributor with a few minutes of good running then back to the same . They are taking it to another mechanic to have him go through it. I have wiggled the wires under the steering column but did not get any noticeable effects. I will have them mess with the steering column wiring while its running to see what's up.

Well my kid (16yr old) has been working with my mechanic and it seems to be running good now. I'm not sure what they have done yet but they have been driving it around town this afternoon with no problems since they tried the other parts. I'm guessing like y'all have said it could be in the ignition switch or a broke wire somewhere in between. The did go ahead make a jumper wire in case this starts up again.

Thanks to lumpy grits I now have a jumper to coil encase I need it. They swapped out the the module in the distributor checked the coil and found 2 wires connected to the clutch pedal . Sometimes POs are idiots . It's ran fine for 2 days and I'm now putting my radio and locking console in. I hope it's gone for a while.

The clutch pedal?

Must be a good story behind that...

Maybe thePO's theft device gone bad?

Clutch pedal wiring just one of the weird things I've found lately. They cut the wire at the steering column to run the radio. I bet I've pulled out 10' of wiring and extra inline fuses all just for the radio. My advice for new jeep owners is to to do more research on your modifications before creating problems down the road.
