2011 GR 2120. First time it stalled 10 amp fuse was blown. Replaced fuse and it worked for about an hour. Replaced PTO switch. It still stalls out after blade lever is engaged. Use jumper to by pass seat switch. Still stalls. replaced seat switch worked about 1 hour then stalled out and continúes to. When it starts to stall if you quickly put foot on brake it continues run including the mower but you can’t mow with foot on break. We are stumped including my local dealer. Help please. Thank you. Walker

If it runs with your foot on the brake the culprit may be the brake safety switch. Check it for proper operation, though it may be intermittent in which case a failure may not show by testing. You could try bypassing it to see if the problem persists or just replace it if not too expensive.

Finally figured it out. When engaging mower deck and it starts to stall …quickly put foot on brake pedal and it then continues to run. Replace brake switch.

What you are describing is a WORKING brake-switch. (The brake switch is doing something when you push the pedal)
I would think the SEAT switch may be the issue.
