Been there and done that on the cast iron kohler engine. They have a bad habit of the exhaust valve sticking when they get hot. Over time, the exhaust valve guide will tighten up due to burnt oil residue and when it gets hot, the valve will seize in the guide. Cools off and will run until it heats up again.
Simple enough to fix as you just have to replace the valve and ream the guide.
