    Have you replaced the spark plug wires or at least inspected the old ones for pinch points, wear marks, burn marks, places there may be electrical leakage, etc. Are the wires firmly seated in the coils and no corroded connections at the spikes? Maybe it is occasionally arcing to ground somewhere and doing it intermittently because of vibration?
