Bingo!
Replacement ignition switches (new or otherwise) for vintage Ford tractors are of notoriously poor quality. Often the tractor will start and run properly for 15 or 20 minutes until the switch contacts heat sufficiently to increase contact resistance enough to diminish coil primary current such that ignition secondary voltage is unsufficient to properly fire the spark plugs.
This condition is very difficult to diagnose because the switch contacts begin to cool down immediately when the engine stops if the engine stops with the point contacts open. Often the spark will appear OK when one attempts to restart the engine leading one to look elsewhewre for a problem.
Tey this: Prepare s short jumper lead with an alligator clip on either end and carry it with you in the toolbox. When the tractor next stops unexpectedly, use the jumper wire to connect the two contacts on the ignition switch and attempt to restart the engine. If the engine now starts, replace the ignition switch.
Alternatively, simply replace the $10 ignition switch.
In either case be prepared for the same problem in another 3 or 4 years.
