First thing I have to ask is does the generator have belt tensioning device? The unit mounting bolt does not qualify as a belt tensioner and hold secure. Is the generator correct: 1-Wire/3-Brush OEM type? You can have a local starter shop bench test gen & battery. Cutout circuit test is in the FO-4 Manual or shop can also do. Get wiring diagrams and verify via continuity. Disconnect any lights -you can reconnect after root cause solved. Don't guess. Problem solve. Get a working AMMETER. When tractor fails to run, check for spark right then. Is the OEM Ballast Resistor in the circuit? The coil can be tested static with an OHM METER. The Battery is the heart, life blood in any circuit. Simply charging the battery does not mean it is good and will sustain a full a charge under load. Some batteries can be junk out the door of the store. Start there and while he's bench testing battery, verify the wiring is exact as should be, no shortcuts. While engine is cold you can also do a fuel flow test, but I suspect your issues are electrical. Again, if generator (or alternator for that matter) isn't kept tight for the belt, it'll never charge.
