After I blow snow for about 20 minutes my tractor will just die. Always starts up after a 15 minute rest. I am thinking coil. Any other ideas? Thanks
 
change out the coil, install a hotter one, what I did on my to35, it starts better.

also when it stops running, is carb icing on the outside, take off your air pipe to carb from air cleaner, it might be freezing up, or your fuel line freezing up.
do you run seafoam in your fuel or stalbuild?

could you have water in the gas? how old is you gas?

when it stops running take a sparkplug wire off and turn over motor, do you get a spark at plug.
if so, then its not the coil,

I am thinking fuel lines may be freezing up, then as it sets for a while, the heat from the motor thaws out the line stoppage

let us know what you find.

if new coil does not fix problem, I would drain out the fuel and add fresh fuel with seafoam.
check fuel cutoff for dirt you could have sediment in the cutoff filter and it will run so long, then stop up. I added an inline metal fuel filter, much better fuel filtration.

on my old tractor there is another fuel filter in the elbow as fuel line goes into carb, do not forget that one, if yours has that!!!!!!!!!!
 
if it sputters, spits and dies it is most likely a fuel issue. if dies like the key was turned to off then electrical issue.
 
The round can coils almost never go bad so not likely to be the problem. What you need to do is trouble shoot before thinking about throwing parts at it. When it dies check spark. It should be a blue/white and jump at least a 1/4 inch gap. If no spark or weak hot wire it and see if you get spark. If you do then your problem is from the coil back if not then coil forward. If you have good spark when it dies pull the carb drain plug and make sure you have a good steady flow of gas.
ALWAYS trouble shoot then parts
 
I bought my first ferguson, a TO-20, back in 1980 a few years after I got out of the army. since then I have bought and sold 17 old ferguson and ford tractors and I can say without a doubt that none of those machines ever had a bad coil. I am not doubting what you say. I guess I have been very lucky. I made my comment based on my experiences with these old machines.
