When I had the manual shutoff I would constantly forget to open it before I started the tractor and moved it out of the shed. So I know there is enough fuel in the bowl, pump, and lines to start and run the tractor for a few minutes even with the solenoid closed while cranking.

You could consider something like this using a 5 pin automotive relay.
With no power to the relay coil pins 87A and 30 are contacted.
Pin 87A is wired to the starter solenoid engage terminal (the "S" lead from the key switch) and pin 30 is the hot lead to the fuel solenoid.
Power on pin 86 operates the relay
With the key switch in the off position the relay is at rest, pins 87A and 30 are contacted but there is no power from the key switch so the fuel solenoid is off.
When the key switch is in the run position power is applied to pins 86 and 87. Power on 86 operates the relay which contacts 87 to 30 and powers the fuel solenoid.
When the key switch is in the start position power is removed from the relay, 87A and 30 are back in contact but the power on the solenoid lead from the key switch is fed through to the fuel solenoid allowing it to operate so you have fuel flow while cranking.
I have not tried this, just dreamed it up from reading your post.
