" EVERYTHING HAS BEEN REPLACED, ALL OF IT!!!"
Some people and electricity should not cross paths.
If you replaced everything then you replaced something wrong... or... You got a new out of the box failed part.
93 Grand Cherokee would die when it warmed up. Replaced the capacitor on the distributor cuz it tested bad. Same symptom.
Changed a whole bunch of other stuff including a $600 computer - no joy. Replaced the capacitor on the distributor again - problem solved
. First one was bad outta the box. Like a $5 part.
