CUDA DIED...NO SPARK to PLUGS !!

Ballast resistor will start motor during cranking (ballast bypass) but wont keep it running in "run" . If that the case, just jump the resistor until you get home and replace. Get yourself a points dizzy and get her home for the in depth diagnostics. You can limp that thing home with a jumper wire from the battery + to the + coil and bump the starter relay with a screwdriver with a points dizzy. Good times!
