I would deffinately check the coil. I had a very similar experience with
my '63 MG (including a coil that was right out of the box!). My only guess
was that the coil got hot and started to fail. The problem was exacerbated
under load in my case too. My B would idle perfectly well, and would rev
nicely too, sitting in the garage, but would run as if on three cylanders
under moderate to heavy load.
