The one thing automatic system failure theory can't explain is whether there is a reverse connect from the machine back to the switches where if the machine decides to cut off fuel, would the physical switches toggle to cut-off or stay in run position while the fuel is actually cut off, this would require an actuator setup to flip the switches from inside the system which there is no documentation of if that is even support let alone reported?
They are simple toggle switches without actuators. The switches are Honeywell P/N 4TL837-3D. Source[1]. Data sheet[2].

Do your lights control your switches?
