96 ZJ Just stops running.
If I start my ZJ in the driveway it'll fire right up but without warning it'll shut off. It could be 15 seconds, it could be 4 minutes later. Running down the road it will shut off during acceleration, while cruising, at a stop sign it doesnt matter. When i'm driving it, the gauges fail and fall to empty on the gas gauge, zero volts, zero oil, zero temp but the tach and speedometer freeze where they were, most of the time they recover and the engine will start running again in a matter of seconds all on it's own. I'm confused as to what it could be. I have new Mopar Crank and Cam sensors, O2 sensors, the grounds at the engine block, next to the battery and the main cable ground have all been cleaned to bare metal and re-installed. The IAC is a new Mopar piece, the TPS checked out ok, the coil wires are routed properly and the coil is not cracked. The computer harness doesnt seem to affect anything as I can grab the harness at several different places when the ZJ is running well and shake, twist, bend, and move it with no issues. The connectors at the computer are solid and nothing changes when I attempt to move those either. I've swapped around the relays to see if I had a bad one, but they all test good too. Fuses are not popped either. I'm at a loss. It's the Wife's vehicle and she wont even drive it until I get it fixed. Ideas?

Traded away the WJ to get a commuter
We finally got another Jeep after 5 years without. Too bad it's ALL stock.
