Jeff,
Sounds like you found it. Couple of thoughts. A) There are some s*&%
rotors out there (sold some by accident) B) This doesn't have to be a
sudden thing.... if there is higher than desireable resistance "downstream"
(wires breaking down, plug gap too wide, etc) the high voltage will seek a
different path, like through the rotor, to ground. Any moisture will also
provide a path which, when dry, will become a track.
Good bit of diagnosis. Can do a lot with a voltmeter and an ohm meter.
Now its just fix and drive!
