It's starting to seem that a wiring/connector could very well be the culprit. This all started after I did the Canni/Flappi and put it back together. Makes sense to me... I'll dig in again and give a slight twist to every connecter pin I can find and use the contact cleaner William has recommended (ordering it now).
Good thing I love this bike!
And I must add: The crashbar and bashplate stud mods are SOOO nice if you have to tear into your bike on a regular basis.
