Yes sir, I believe you may be running on just one cylinder. Exact same symptoms I experienced a year ago.
To test this theory: Take a pair of pliers with rubber grips. With engine running pull a spark plug wire off. If the engine keeps running you know the opposite cylinder is still working. If engine dies you know the opposite cylinder is not working. If it continued to run. Kill engine. Hook up spark plug wire again. Start engine. Then disconnect the opposite side spark plug wire.
I had same problem on a commercial zero turn a while back. It ended up being a bent push rod that wasn't allowing a valve to open/close.
Hope this helps.
