You could try another resistor, but what you describe is a classic coil failure.
There will be a small break inside it somewhere, that when cold/cool and will complete the circuits needed to make the field. As it warms up, this slight break will separate, break the circuit, and - - no fire, just as John T describes. Let it cool down and it will run for another short while.
For a replacement coil, there are two ways to go. The presence of a resistor leads me to assume the tractor is running on 12 volts. The thing to keep in mind (technically it's a little off, but the concept is right) is that the distributor wants only the output it would get from a 6v coil, whether the tractor is 6v or 12v.
So there are are two kinds of 12v coil. Your parts guy should know which is which.
1) Is the type that is probably there now. It is actually just a 6v coil, and requires the resistor in the line powereing it to drop the voltage to 6v.
2) Is designed to take a full 12v in (i.e., no need for the resistor). It doesn't have a resistor internally, but is wound differently, so that the effect is the same.

Today's Featured Article - Roof Palomino - Tractor or Jeep? - by Steve Nelson. My father-in-law purchased this jeep-like lawn mower back in 1968. He says he paid $1600.00 for it, which was big bucks back then for a mower. My own father bought a VW bug the same year for the same price. Well it
