Jeep keeps stalling help!!

I bought my 89 wrangler about 2 months ago everything was fine than it kept stalling out eventually it wouldn't turn on but it would sound like it was trying to. Currently it still stalls after driving it for awhile when the Jeep makes a stop. I have put various new parts in it but the Jeep still stalls if anyone has had this problem before or and idea what might me wrong please let me know. Just want to be able to drive it. Thanks.

I replaced....
Distributor coil for the distributor, fuel pump, gas filter modulator, plugs and wires, a new carburetor, whole exhaust system.

Did you replace the distributor wit a stock unit or something like an H.E.I. distributor?

Same goes for the carburetor, Stock or aftermarket?

If you have an aftermarket carb, and a stock distributor, then you have to perform what is called the "nutter bypass"(Google it) to take the computer out of the equation. On the 4.2L motor the computer controls the stock carb and the distributor, and makes adjustments to each as you are driving. If you replace the carburetor, then the only thing that the computer can adjust is the distributor, and this leads to erratic idle, and constant stalling.
