I agree with Randall. Ignition is more likely the culprit from the symptoms
described, and the coil is a possible offender. Coils don't like heat or
vibration, and so Triumph put them right where they'd get as much as
possible, on the engine itself (maybe the tractor heritage). If you aren't
concerned about pure originality, relocate it to the inner fender well. I
did that with all my TR's, and never had a coil failure since.
