Possible problem fix
I am having the same issue with my Jeep (96 GC limited) I can drive it for days with no issue then suddenly BAM it dies while driving at normal speeds and sometimes starts righ tback up other times takes a while. It feels like running out of gas at times, chugs hard while dying then either picks up perfect or dies. I read on 4 other websites about 2 screws holding the cover to the PCM causing the problem (the ones directly under 2 of the connectors). It stated backing them out some and trying, or replacing with a longer screw and not fully tightening it. On all sites this fixed the problem and only cost at most $.50 from Lowes. I also think the fuel filter could be clogged so I will also change that on mine as it has 147K on it and im a recent owner so who knows if it has ever been changed. I hope this helps all of us!
