check your electrical system. Your alternator may not be putting out full charge or your battery may be on it's last legs. An engaged PTO needs around 4 amps of sustained 12 volt power to stay engaged. Even a loose or corroded battery or chassis ground terminal can cause trouble.
I had the same problem with my 1999 yardman (another MTD product) a few years ago. It turned out to be this thing, I forgot what it's called but it was in the wiring harness behind the dash. Yours is 6 years newer and may be totally different.
