For over a year now, we have been experiencing an intermittent problem of our B21 quitting. Today I was moving forward slowly when it quit on me. When I try to restart, the fuel solenoid does not engage, audible click. This happened to me 3 times within the first hour of using it, after that it ran without a problem for 2-3 hours, turned on/off whenever I needed, never quit. We have been told it could be one of many things, Ignition switch, fuel solenoid, safety relays for PTO, Clutch, Seat, forward/reverse, etc. With it being intermittent like it has, what is your recommendation for troubleshooting?

There is no "easy" answer for an intermittent problem. You will have to check every connection and tug on every wire, looking for a bad crimp or loose lug.
Since you suspect the fuel solenoid, that is a good place to start. Get a voltmeter, and look for the source of low voltage.

You can attach a meter to the farthest ends of the wire chain for the solenoid and put it in Ohms/audible mode. Then start wiggling and tapping components as you go. When you can interrupt the meters 'beeeeeeeeeeeeeeeeeeeeeeeep' sound reliably, you've probably found your problem.
It doesn't work every time, and certainly not all the time but when it does it's very nice.

If you use this method, remove the battery cables before you do anything, power on an ohm meter will toast it in a sec!
Good advice about removing power source (battery) from the system. Hitting an ergized circuit with a low-end ohmmeter will kill the meter---you'll hear a pop followed by the 'magic' smoke leaving the meter.
Higher-end digital meters should be circuit-breaker protected.
If you are using a digital meter, some will switch from the audible tone to a numeric display at some preset ohm reading.
For the type of circuit searching you're fixing to get involved with I find an analog (needle) meter---cheap, easy to find, easy to replace---the better way to go. I like seeing the needle bobble as I jiggle wires compared to sometimes the beeper won't respond that I can hear it.
Please post back your experiences and problem resolution so we may all learn.
