Jeremy Holmes , Check/verify that you have the correct size belt installed and if worn/stretched replace it, then make sure all the belt keepers/retainer guards/guides/pins are in place and not bent away from pulleys too far(allowing belt to jump off)1/8" gap is good.Ensure belt routing is correct,check for worn bent pulley's or excess debri around them, level the deck.

Check your pulleys for wobble and make sure your belt is the right belt.

if that don't work for you use a smaller belt it will be hard to put on but it will last forever.
