If you know which cylinder is having the trouble, at least you'll reduce the possible sources. Also, you'll be able swap components and know when you've found the culprit, since the cold exhaust pipe will move.

Welcome to the board, Brian!
Unfortunately it doesn't run long on that one cylinder before dying or magically getting both back once I come to a stop. Hard to tell which one is failing. Although I CAN sustain that one cylinder for miles at speed so a temp gun on the exhaust might let me know which of the two is cooler once I pull over.

I trimmed the ignition cable between the plug boot and coil so we'll see if that helped. Time will tell and if not I'll try to identify the side and swap or replace components.
