Simplicity Zero Turn 16HP Hydro Model #1693473

My Simplicity zero turn 16 HP hydro lawn mower will start when my foot is applying pressure on the brake pedal, but when I release my foot from the brake pedal, it turns off. I checked the safety switch and it works. I don't know what happened, it ran well the other day but suddenly it doesn't work. Can someone tell me what might have happened and where on the machine it could have happened? Thank you very much.

Do you have a seat safety switch? That may be the one that's not working.

Thank you for your help.
Yes, it have a safety switch, but I tested it ready, it is good. Switch had 4 poles. 1 pair open and 1 pair close when switch press down, when release 2 pairs action opposite. It mean it is OK,
I do not know why machine start when press break pedal and it stop when release pedal.
Someone help me,

Push the connector tighter on to the seat switch and see if your problems go away.
