I have a Toro Zmaster that after about 2 hrs of mowing it stalls, I am able to restart it back up in the safety mode.

Any suggestion as to what the problem is

Need the model and serial numbers to see if I can find the service manual and how it is setup. Should be 5 or 6 digits long for model number. Serial number would be longer.
