Jeep Dies

I am having trouble with my Jeep dieing. It will just die from time to time when going down the road. Usually two or three times every 200 miles or so. So it's not that often but it's not good when it dies in traffic. It will fire back up if you wait about 10 or 15 seconds before trying to start it again. I know it's not a fuel problem cause it will flood if I leave it in gear after it dies. I have replaced the plugs, plug wires, distributer cap, and coil. I have a direct wire going from the coil to the battery with a switch on the dash so I know the coil is not losing fire. The ground on the block is tight and clean. What have I missed? Any suggestions?

when was the last time you changed the fuel filter.

Fuel filter is clean. I really think it has to be an electric problem. When it dies it doesn't stutter or give any warning. It's just like you turned the key off.

I am thinking it may be the ignition module. I have the motorcraft carb so it has no electrical controls and since I have a kill switch in line on my wire from the coil to the battery is there not some way I could bypass the ignition module?

No way to "bypass" the module, you have to replace it with something. Either another type of distrubutor or another module.
Those duraspark modules are know to go bad all the time on Mustangs, but I haven't seen much discussion of them here.
There is a way in the mustang world to use a GM module, but I thinkyou might as well replace the one you have. Ot get the HEI distrubutor upgrade evryone here recommends.

It definitely sounds like an electrical short in the ignition components, however it sounds like you covered almost everything.

My 95 2.5 wrangle behaved similarly. I put on a new ECM, coil, dist.vcap, wires, plugs, etc and it turned out to be a weak point on the power wire to the coil. The wire right at the connector was visibly fine, however once it warmed up it would short out. The coil was mounted right beside the engine block and the small guage wire was subjected to intense heat. I bought some connector pins at Autozone to fit a jeep and cut out a short piece of wire at the end and reused the plastic connector. It worked great after that. I think the wiring on jeeps may be only second to transmissions as a weakness for the brand.

If you spliced direct power to the coil wire (and not directly to the coil), you should check/replace the old connector pins
