You previously posted about this issue on the "Farmall Forum", and a couple of us tried to help you, with no reply from you.
You've apparently given up on us (without the courtesy of a reply), and smuggled your problem over to this Forum.
You need to tell us (as I replied before) if it's actually losing spark when it quits running and coasts to a stop.
You ask "if 12 volts isn't always supplied to coil will that shut it down".
OBVIOUSLY the ignition can't make a spark if the power supply to it is interrupted. "12 Volts" is "nominal", when the engine is running the voltage ahead of the ignition resistor (which you say you have) is probably around 14.5 Volts. My advise,in addition to checking the spark as it dies is to monitor the voltage supplied to the coil while it's running well, while it's dying,and after it stops.

If it would just start when I turn the key, then I would use it more often. In addition to a bad case of old age, most of the tractor's original electrical system was simply too unreliable to keep. The main focus of this page is to show how I upgr
