Welcome to JUST ANSWER small engines, let me try to help you !! Check the seat switch and harness connections to it. The mower thinks there is no one in the seat, so it shuts the engine off when brake is released, or blades are engaged.

Is engine staling, or is it cutting off like you turn it off? Will it roll free if you pull free wheel lever? Do the blades rotate freely with engine OFF and pto not on?

Has to be a safety switch or harness to one of the switches. Seat switch is a two contact switch. One should be N/O, the other N/C. do they check out and change when seat switch is pressed. You have two circuits, one for start, and one for run. The run circuit is not complete.
