As it was running fine, and then just stopped and you presumably did not make any wiring or mechanical changes between it running and it failing then I don't see how it can be things like plug lead mis-ordering. It seem much more likely to be a component failure. I know you have tried changing the coil and the ballast resistor. Is it worth replacing the condenser? Where physically are you located ? Are you anywhere near a dealer ? I would also suggest putting a hand over the exhaust pipe and confirm there is some outflow from the engine when you are turning it over with the starter to confirm that air is flowing into and out of the actual cylinders....
