Well, the problem appears to be resolved. Pulled the dizzy, replaced the mag pickup, cleaned things up (amazing how much corrosion/crap can get inside one of these things) and reinstalled. The problem appears to be resolved, so I'm pretty sure it was a bad pickup. The real test will be firing it up after sitting for a week, but I'm guardedly optimistic.

Thanks for all the good advice/suggestions. I really appreciate it!
