Going to assume your alternator is fixed and is no longer the issue.
Are you saying the engine turns over with the starter but never fires? If that is the case:
These things have huge 44 gallon tanks so the fuel pumps tend to give out, especially if you run below half a tank a lot. When you turn the key to the "on" position, just before the the starter kicks in, can you hear the pump? If you can't hear it, try rapping (gently) on the tank with a rubber mallet. On mine, this would sometimes jar a cold connection or something and make the pump turn on. You can also check fuel pressure at the schraeder valve on the fuel rail.
