Thanks for reporting, Tom. When I read you suspected the Pertronix I 
thought: "This is the first I've heard of an Ignitor becoming 
intermittent (I'd always heard they failed outright."

      <div>That was to pull and replace the Pertronix Ignitor.  As I was
        taking it out, The cause of this whole mess became apparent. 
        The hot wire from the Ignitor to the coil had been rubbed raw on
        one side of the wire, exposing just a tiny amount of the inner
        wire.  It was this small amount of exposed wire that was
        shorting intermittingly.  and this was the source of my
        problem.  </div>
      <div>Apparently, over time the rotor had rubbed the wire until it
        rubbed enough insulation off to expose the wire. This shows how
        long that Pertronix had been in there.</div>
