A good way to see if the valve clearances are too tight is to run it til it gets hot and stops. Check the compression then, if it has compression, the valves aren`t staying open.
What's Wrong With This Engine ? ?

I've also seen a blown head gasket act like that , run fine till engine heats up and then sputter and lose power and die after 10 to 15 minutes . Usually accompanied by a little black smoke right before they die . A quick check for oily residue around the head bolts will tell you if its got a blown head gasket . I've also seen a sticky exhaust valve cause similar issue if there is carbon buildup on it .
Same here, check the plug before and after it heats up. If it's oily then clean it off and try running it again. Happened to me and after a HG replacement she runs great!
