Howdy,

I had a similar thing a long time ago with a more modern car... '99
Camaro.  That did turn out to be grounding related (specifically, the
grounds between the engine block and the chassis).

But in my case the car almost never ran right, vs. it only occasionally
having a problem.  Not to say that you couldn't be on a similar path of
course.  Given that its fairly easy, I would definitely just run a
completely new / separate grounding wire from the engine to the chassis.
Maybe even one to the frame and one to whatever sheet metal your ignition
stuff is mounted on / getting its ground from?

I also wouldn't rule out the new harness if everything else checks out
either though.  You wouldn't be the first person to have a brand new thing
have an issue.  I assume you've carefully inspected all related connectors
for a pin that's not fully seated, etc. etc?

Good luck!  With my Camaro after dicking with it for a year or so, I took
it to a very well respected mechanic with instructions to either fix it or
burn it.  At that point I didn't care which way it went.  :)
