Cub Cadet LTX1040 stops moving sometimes

[semimechanicman]

I have a cub cadet ltx1040 and ran good and all but when I press the gas pedal it would move for about half a second and then come to a stop. Then I would press it again then the same thing would happen over and over, after that it started moving normal. Anyone have any ideas?

I would check the condition of the drive belt. Mine did the exact same thing one time and i replaced both drive belts primary and secondary belts.
