Cuts out for no reason... other times stumbles

I have a 90 jeep... 42,000 miles. I bought it used from a young woman from whom I got the impression liked the idea of owning a jeep but not driving it.....

I have had it for about 2years... ran okay.

Recently had major problems(as I fear a lot of us have) with the carb, intake/exhaust values, cat, and muffler. Replaced them all.

Runs better than it ever has... when it runs.

Occasionally, (3 or 4 times in a 2 month period) I have been idling at a light.. light changes, I give it gas and my tack flies all over the place as it "stumbles" forward...Tack reads 0 then shoots to 21/2 back down to 0. Twice it cleared by itself... twice I chugged to the side of the road... shut it off pulled the air filter/carb cover off... restarted it and all was fine...

A couple of times, (2 or 3 times) I have been idling at a light.. and chokes and dies... sometimes it starts right up...

Last night.. I was driving home... doing about 45-55 mph... it dies... my foot still on the gas... I pulled over... tried to restart a couple of time.. no luck.. got out and removed the air filter/carb cover again and she fired right up...

On way home... tack dove to zero twice.. but it did not stall.

I brought it back once... guys couldn't find anything wrong.. plan to bring it back again. I'd like to point these bozos in the right direction...

Any ideas...anyone..anyone at all. Help!

Check your Distributor Rotor.. make sure there is enough for contact to the top of the distributor cap. It might not be your air/fuel mixture. It very well could be the electrical side because if you are on the highway and as everyone knows each Jeep is a brick with mudders, the jeep will get more than required air into the TB (Throttle Body). Also when the contacts get warm or hot the metal of the rotor will be more plyable that cold.. that also might be the zero to 2,500 RPM deal..

See y'll on the trail.
