Your explanation of a voltage drop during OFC is interesting, certainly a possibility. During OFC, the engine is stalled! It is firing the spark plugs, but not injecting any fuel. So more than semantically, its not running, just being pushed by the rear wheel.

If you were in OFC, say decelerating from 5000 RPM, and at 2500 RPM pulled in the clutch, the engine has to catch with very little rotating inertia--only what is has from its own mass, the rear wheel isn't driving it. I'll have to try that today when I'm out riding.
It would be nice to know at what RPM it actually dies at. That would help paint a better picture
