Hi!

The problem with my mower does not seem to be related to engine.

The engine starts strong and does not seem to exhibit any issues.

However, as soon as I let go of my brake pedal, the engine quits as
though some kind of plug has been pulled.

as long as I have my feet pressing on the brake pedal, the engine runs
fine.

I was thinking it is ignition switch issue (since the ignition system
is designed that the engine will not start unless the brake is
pushed), however, if that is the case, I would think the starter
motor would be continuously running (if switch is stuck at the start
position) but it does not seem so.

It just happened suddenly, without any notice. I was mowing and poof,
engine quit. Since then above issue was happening.

I am miffed.

Thank you in advance for your help.

I agree with hpark. It sounds like the seat switch. It allows the
engine to run as long as the brake is on but will shut it down if you try to
move it without someone in the seat.
