Mark,
There may well be a duty cycle problem, but I doubt it. Older ignitions used a single coil of similar type firing all 8 cylinders. I would be more likely to suggest it was a "bathtub failure curve" failure of the solid state "trigger" circuit.

Sorry, that's what I get for doing "head math". Anyway, my point is still valid. It fires 8 times more often in the rotary than in the truck/auto. Could the duty-cycle be the culprit? It would be interesting to see the specs on these coils.
