I have a 7.5r27 kohler marine generator has less
Given the work you have done, you never mentioned if you have had the stator and rotor tested? if you can get it running check for DC power on the brushes. that will help isolate. If power blinks for a second, that is the control trying to flash the rotor, if the rotor has a short the controls will remove the excitation voltage. Check that before going to any major expense

After 8hrs of continous operation
Aux fault is caused by a momentary loss of voltage from the speed sensor or low coolant level sensor. I would suggest you investigate both for possible cause.
If the unit has a low coolant level sensor you can find it near the top of radiator, small two wire plug. Disconnect and see if unit runs. make sure radiator is filled to over flowing before testing to eliminate this as the cause. Just because you can see or feel the coolant is not enough, fill to overflowing is the key.

20hp kohler horizontal engine will make loud metal
the chirping you hear is probably from a worn cam or valve lifter.
usually these engines use an oil slinger to throw oil around the crank case.
if the oil gets too low parts will wear away faster.
sorry to say but your engine has probably had it and is due for a rebuild.
always keep the oil at sufficient level and change it regularly
