Did either of yall have any luck? 96 suburban EXACT same issue. Will only run with cylinder 3 plug wire unpluged. Plug that one in and it kills the truck instantly like I turned the key off. Died out of random while driving. Been scratching my head for months and finally found this one and only forum where others have had the issue.

Not an answer, couldn’t figure out how to reply. I have the same problem, just curious, are you using AC Delco cap and rotor. I bought the cheap one, was thinking maybe it was the problem
