Mine died in exactly the same way. Turns out the small diameter red wire
coming from the battery positive had worn thru the insulation, and over the
years, trace amounts of battery acid, debris, and water finally dissolved
the copper wire. It was the wire to the ignition.
Engine would turn over, electric to everything, but no start due to no power
to ignition circuit.
Wire was spliced together (and well insulated now), and it runs fine.
