I am thinking you have the 20hp kohler.
first pull the fuel bowl and check to see if the float valve is stuck and not allowing fuel to enter the carb.
Second check your wiring, some of those units have a fuel cut off solenoid on the carb and any tripped safety switch will make it shut off.
always make sure your safety interlock switches are working.
Those engines have a bundle of wires that come very close to the exhaust and tend to melt with the high temperatures.
probably the governor going bad
I have problems whit the Injectors fuel on 6520 John Deere Tractor, same times the engine stop and wait for few seconds and. start again.
check the torsion dampener.

John Deere wasn't shot. He died at home on May 17 1886. of natural causes.
Joh Deere puts the body on a Deere Chassis with a Ford Engine and Tranny
Put a voltage meter on the battery, Note the reading, and start the engine, the reading now with it running should be higher. I would be happy seeing 13 to 14.5 volts on the meter with it running.
The oil capacity of a John Deere 2020 is about 7 quarts.
Actually,John deere coast much than New Holland but works less,Yes i have experienced it , it is due to their engine power New holland has a small turbin but a powerful engine but John Deere has a Big turbin but engine power is less ok
The most important thing is the engine. The rest is all the same. Look for anything with a Briggs and stratton engine and you will be fine. What a dumb answer. Deere by a landslide!
A John Deere 3020 takes 9 quarts of oil in its engine. See related link for more information...
yes he died of natural causes
