I believe that a diagnostic check on your vehicle will indicate

that the security module (black box) is failing in some way. I

experienced the same with my 95 and as it got quickly worse the car

would die unexpectedly as well. Since I live in a small town and

feel very safe I rarely lock the Jeep and so have no real need for

the security features. I unplugged the module and the problem was

immediately and completely solved. On my 95 the module was under

the dash and is about 3 inches square and black plastic and clearly

marked with the name "security module". It simply unplugs. Unlike

other modules that plug in here and there in these vehicles,

nothing else is affected by unplugging it and no dash lights light

up as a result. It would be free to get a flashlight to see under

the dash and try it as all you have to do is plug it back in if

that doesnt solve the problem.

The dealer can read your system for a nominal fee and point you in

the correct direction also.

I know you can purchase replacement boxes but they are expensive

and I'm also sure that you could find one of them at a junkyard for

far less cash. I wouldve pursued this myself but my dog ate the

clicker and its $90.00 just to get a new one.

Good luck to you !!!
