I had a similar problem. if I would jump on it, as soon as it would hit 4000 it would backfire super loud and shut down, 3 seconds later if you start right up and I would drive away. the problem was the crank sensor pigtail. I bought a new pigtail, soldered it in place and it was perfect again....all this after 2 months of trouble shooting.
