Factory Alarm Problems on 1993 Jeep Grand Cherokee

Factory alarm system has randomly engaged stopping fuel flow and preventing re-start. Re-set randomly works. Have disabled at overhead console but still experience random stops. How do I disable perminantly?

Unfortunately, You cannot disable the factory alarm system. It is programmed into the Powertrain Control Module. Possible other causes are Hood, Door, Liftgate or switches. Powertrain Control Module (PCM) Key lock cylinder switches.
Is it possible that it could be the chip in the ignition key? I have the same problem on my 96 pontiac grand am gt 3100
