ExMark want start if turned off after 45-60 minutes of mowing

[BabyDaughter]

I have a 2012 Exmark Lazer Z, S Series, that mows fine but if you need to stop after 45-60 minutes of mowing, you have to want 60 minutes or more for it to crank again. Air filter has been changed, the recall part has been replaced. I have slowed down the speed of mowing. Do not know what else to do? Dealer did not help.
