x595 Stalls when brake is released. Help?

I greatly appreciate it.
I just replaced both the brake safety switch and the reverse safety switch. I have also jumped the seat switch in order to rule it out. I have a know good pto switch and I tried that as well.
When I first replace the brake switch, everything seem to be good. I put the mower deck back underneath it the blades would engage and I went to mow. Halfway around the yard it quits again. Same problem. Released to break the engine quits. As soon as the brake light goes out it shuts down

Are the relays closing when you turn the key on. There are 3 black relays I think on the right side, one is the K3 start relay, one closes for the glow plug circuit. the other is the over temp relay which doesn't close unless there is an over temp. Try switching that one with the start relay to see if that is the problem. Also try cleaning the fuses on the circuit board,I've had them cause problems, they gray/white corrosion on the tabs.

I see the relays and I will try this to see if there is any difference. Thanks for the heads up.

Brake switch seems to be working or the machine would not crank with the brake pushed.. Right?

Glow plugs,, shouldn't matter if those are on or off once the engine is running.

Temp over ride relay is interesting but I am not sure the brake would allow the engine to run if the relay was not working.

Are you sure the seat switch is jumped correctly and has good contact? Just trying to think out loud here.

It's also possible one of the connectors is pulled back out of the plugs on the safety switches, etc. This happens from vibration and the plugging and unplugging of stuff.

I would replace the seat switch and actually check the wires inside of the plugs to make sure the terminals are all of the way into the plug and making contact. Check the wiring carefully as it doesn't take much for the terminals in the plug to pull slightly back and cause a intermittent connection.

The seat switch is a common one as that wire really gets moved around with use and flipping the seat up, etc. Replace the seat switch AM131868 as its only $9.68 and they go bad. Sometimes, the bypassing doesn't connect as it should.
