When was the last time electrical connections were made clean and shiny? Especially both ends of both battery cables and both ends of each wire from the battery connection at the solenoid, to terminal block, ignition switch, resistor, and coil. The ignition switch itself can become a resistor. The ignition resistor can get so old it does the job too well. If all those are corroded, rusty and dirty the engine eventually barely runs if it will even start.
