Scag Tigercat dies

I see, the fuel pump in the Kawi parts manuals. This adds to your trouble shooting, as you need to know if it is getting power with the key on and if it is working. Also wired to the same connection in the engine harness is the carb fuel shutoff solenoid. I would check for power to these two items at the engine harness connector with the key on. Also I would check the ground connections where the battery ground cable connects to the engine, this is another problem area due to corrosion and vibration. Fairly decent wiring diagram for this machine. The relay in the middle of the diagram is the cranking relay, green wires. You see the green/black going to the interlock module, when all the safety circuits are in the correct position for starting, the interlock module will ground the relay and let it send power to the green/white to actuate the starting/cranking solenoid. Have you checked all the fuses??

Yup, I checked all the fuses and installed new fuel pump, and checked the flow, previously, but I haven't checked the ground to engine, nor fuel shut-off solenoid. This will give me something to do.

Bryan, From what you've described, I would with hands on look at neutral switches, loose connections, broken or burnt connections. Take a look at page 64 item 12, showing 3 switches, page 65 switch part number 481637 and pages 70 & 71 wiring schematics for your particular tiger cat dependent upon engine manufacturer. If you have a multimeter you can check switches for continuity, they are inexpensive at sears, look online.
