my craftsman riding mower runs good for about 10 minutes blades engaged cutting good at the suggested speed after about 10 minutes it slows up I have to push the speed to full just to get it to move. The drive belt is new and all other belts are new. I checked all the pullys are moving as they should. It seems like when it gets hot it slows down and then just stops..... at a loss. Can anyone help?
