1061093
good news is that i had the identical problem in my 92 yj 4L. just like someone reached down and flipped the ignition switch when you weren't looking. then no reply on the restart.
and i fixed it.
bad news is that i fixed it during my rebuild (all but short block) so i can't really say what part did the trick.
good news again - i researched for days and many mechanics to find the fix.
here goes. . .
first how many miles on the motor? is it time for a crank position sensor? they're notorious for doing what you describe. just for fun, in your web browser’s address box, type in: 'jeep stalling' and read very similar experiences with the crank sensor.
the coil is another possibility.
what i think was the cause of mine was the ignition switch on the steering column. think about it - seems like it was just switched off, right? in that 93, how many times do you think your switch was cycled and compare that to how many times it can be cycled before getting bad contacts?
i also changed my fuel pump because with a hundred thousand miles, it was worth knowing i had a new one back there.
you may find it helpful to jiggle the key when she's running; it's worth the diagnostic time to just change the switch. $10 and about 30 minutes. if you have high mileage and 10 years, there's one good start.
let me know.
