[AT] Ford 4000 Quitting Afer Running a While

[jtchall at nc.rr.com]

I'm suggesting a shotgun approach--points, coil and condenser. Mine and 
dad's experience has been coils go out pretty quickly, as in seconds not 
minutes, leading me to think it could be the condenser, but I'd bet on the 
coil first. Considering the tractor is not at your house, it appears to be a 
bit of inconvenience to work on it, that’s why I'd change it all and be done 
with it. If all that doesn't solve the problem, I'd look into vapor locking.
