I am having the same problem, Just started yesterday 9/26/22. Was running great last week no problems. Now you start the mower ease out on the brake it dies, you ease up on the blade lever it will die immediately when you move it before the blades ever engage. replaced safety switch under seat, No change. I think the answers being given on here are incorrect and not helping, Everyone of them head to the seat or bad gas or frozen pully or shaft, Is the safety switch under the seat the only safety switch on the Mowers or do those other two levers mentioned have safety switches also, The Brake and blade lever. And is there a switch on the park brake? I know there has to be a way of the seat switch to know the park brake is on because it will not shut down when you get off with it engaged unless the blade is engaged. I mean there are many different scenarios here and the posters seem to be zeroing in on one safety switch, Are there more safety switches? I need to know. before tearing a riding mower down so I can see all associated wiring and find out there is no more.
