Have a 4.2 in a 88yj.
When driving down the road the motor just stops running. Turning the
ignition to off and then restarting the motor only way to get it running.
Thinking its the ignition module, but the either works or not and resetting
the ignition should not have an effect, I'm thinking.
If it is the module is this bypassable or am I forced to change the module.
This one is for you Mike, I'd would appreciate your help. Just rebuilt the
motor and installed got about 275 km before this started. just had all
vacuum hoses checked and installed properly. One hose is chaffed pretty
good coming from the evaporation canister.

O, it is excellent to have a giant's strength; but it is tyrannous to use it
like a giant.

Check your distributor cap and rotor, plug wires etc, then especially check
your Crank Position Sensor. If this is bad or going bad, once it gets too
hot, it will cut the engine off.

Don't have fuel injection, the 4.2 is carbureted.

Hi Matt,
If you have to play with the ignition switch than that's where your
problem is, and not in a short, or bad connection, or even the brain
box. You may get a few ideas from:
