That resistor is part of the switch, the entire switch gets replaced. That resistor would be hot if you were feeling around in that area during/right after running. Hook a test light to the coil post the wire from the switch connects to and run it. If the light goes out when it quits the problem is likely between the coil and switch, if the light stays on the problem is something else; like coil, points, condenser or fuel. Check inside the distributor to be sure the condenser wire, or something else isn't grounding out after it starts. If you replace the coil you will need the right one to use with the ballast resistor on the switch, unless you replace the switch with one that does not have a resistor. Also what brand distributor does yours have? Delco and Prestolite used different coils. Some Prestolite distributors have a small nylon insulator on the tab where the point strap, condenser wire and wire from the coil hook together. Those can breakup and fail.

You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
