This was a real head scratcher. Mower would shut off whenever the brake was released or pto was engaged. even with all the lockout switches disconnected I was still getting a reading to ground on the yellow wire which cuts off the ignition. All the switches tested good. Finally found that there was a little spring in the plug on the harness side where it goes to the dead man switch on the seat. I assume that it's there to prevent you from disconnecting the switch because when it's unplugged it connects the ignition wire to ground. Problem was that it was still shorting the 2 wires together even when it was plugged into the switch. Removed the spring and problem was solved. Still shuts off if you leave the seat with the pto engaged or the brake released.
