It might be coming off because it is slipping on the drive sheave during
startup. I have noticed that flat belts often come off when they slip. Just
a thought.

Not sure about the 1/2 twist thing, belt dressing might do the trick
but seems to be just a temp fix....I'll bet I assumed "close enough for
government work" was close enough, maybe I should re-check the
alignment when I get to the shop next.
I was just wonder'n if I missed some sort of "that always happens" kind
of thing......

Thanks guys
