When I pull the handles in on my mower to disengage the brake and drive it keeps cutting off. This is happening more frequently lately but has been happening for a while. Any idea what could cause this? After a while of letting it run and keep trying it will work. See video of symptoms.

Thanks guys. The seat safety switch has been temporarily bypassed because I was having some issues with it before with the blade engagement. The cutting off issue did about the same thing before I bypassed the seat safety switch and after so it can't be that. Any idea where the parking brake safety switch is on this mower?
Sorry, I was thinking of a different unit. Your's does not have a parking brake. I'm now thinking it is either the kill relay or the PTO switch. How old is this unit, they have not been out that long?
It's a 2011. I don't think it's the PTO switch. I have recently replaced it when I was dealing with the blade engagement issue and it was doing the same thing with the old switch.

Your kill circuit is not standard, but looks to be handled by the Brake Actuator.
But looking at the video, it almost seems that the engine is shutting off because the fuel solenoid is shutting off, unless the Brake Actuator accounts for the delay.
Just to test, unplug the kill wire going to the ignition module and see what happens. Also, take a test light, and turn the key to ON, and test for voltage, you should have voltage at the B,I, R, A posts, if not, then the keyswitch is acting up, of course also check both sides of the fuses.
