yes i did a serch...
i have a 91 4.0 5 speed.
when on the gas fairly hard 3000 + rpm. the whle jeep lerches like it just dropped the tranny. then back fires and dies. pull over to the side of the road wait less than a min. it will start back up and im on my marry way. just as long as i do not open her up. i just got back fome a 5000 + mile trip. drove the jeep to florida from utah. and no problems the whole time. was out side of evenston wyoming. when this started. seems to be getting worse. :wow:

long shot but it could be your cat has come apart and under hard acceleration the broken piece gets flipped up and blocks the exhaust flow causing your problem just a quick guess though...Clint it did happen to me..... :eek:
 
I had almost the same symptoms and no check engine light to my 94 XJ a few months ago It turned out to be the fuel pump. Get your fuel pressure checked out.
