When I re-curved my distributor, I had wiped my index mark off my reluctor during cleanup and installed it upside down by accident. I had the same exact symptoms, pulled distributor and turned reluctor over, problem solved. But, a thorough recheck is in order, it's usually the minor details that lead to the most trouble. One terminal, two wires crossed. This is basic knowledge and you probably don't need it, but it may help others out.
