As a non mechanic I'd suggest getting new sparkplug wires (radio suppression
type). There is a resistance
in them to RF so that they don't radiate. This RF resistance will reduce
the peak current and maybe extend rotor and cap life. Beyond that I'd guess
maybe a bad connection or bad electronic module. One would be hard to find
and the other expensive.
I'd schedule an appointment with a mechanic that has a automotive scope.


Thanks. All of that has been done! That's why it is so frustrating.
