This could be electrical or mechanical not sure. When I start off after the Jeep sets for the night and after proceeding a mile or two the engine stops as if the key was turned to the off position. While still rolling, I push in the clutch, trun the key to the off position and restart and the engine starts up again. This continues to happen several times for the next 10 to 15 minuts. After that it does not happen again and I can drive for the next 100 mile with out a problem. I have replaced the module, coil, reluctor, cap and rotor, fuel filter and plugs. Thank you for any help or suggestions you may have.

I'd probably check the feed to and from the ignition switch, when the problem is ongoing. Another way, although it may be inconclusive, check any fuse that is ignition feed.

In response to you reply and thank you for same. You indicate to check the feed line to the ignition. Why would this happen only when driving for 10 to 15 minuts and then the problem goes away and not happen again until the next day after the vehicle has set for the night? Thanks again.

You mentioned cycling the ignition switch, my first thought was check the feed circuits to and from the ignition switch, when the problem is ongoing. The problem may not be those circuits at all, you have to start somewhere?

The next time it dies on you, don't recycle the switch, just leave it on. Check for primary voltage at the ignition coil, use a testlite. Primary voltage to the coil comes from ignition switch.
