I had thus issue after installing a new carb. I forgot to set the float height. The jeep would die after about 4 miles or so. Try setting the floats, might do the trick.

My brother has a 1982 CJ5 jeep pickup with a 360 V8 engine. He is having trouble with it shutting down every two miles. It restarts after setting a few minutes,then does it again. He has checked the catylic converter,put in a new fuel pump,coil,distriubter and a new brain box(as He calls it)on the fire wall. Any ideals would be most welcome. Needs it running. Thank you. my e-mail address is jimrosalie.sears@g-mail.com
