I have 4840 Gehl skidster and it will start up fine and run for about 10 minutes then it will shut down and it will start back up and shut down again. I just replaced the fuel pump too.

Sonds like a sensor putting out an error code to shut it down ( like a fatal error code) Prolonged vibrations and heat can make cam sensors, maf, o2 senosr do craz ythings which will actuate a govener and stall your car...could also be you fuel pump causually telling you that "hey im bout to die".I dealership can run a stress test (if you will) to check the longivity of the pump...
Good luck hope this helps :)

I suggest that you chech the pickup filter and the normal fuel filter for contamination.

Replace the coolant sensor. If the system were to decide that it is too hot, it can shut down, after the "limp home" mode runs out.
