Yes I did once. It was rod knock. Spun a bearing he next day.

When it knocks under load, to me its almost always got to be the KS
system. Are you sure everything is working right?? Just because the
timming is set perfectly doesn't mean the KS system is working. Be sure
to look into that. 
Now, if it tapped at high rpm under any throttle position, then it would
be low oil pressure to the lifters. If its rod knock, you would know
because it sounds like the bottom end is comming apart. (Because it IS!)

Its not the engine that is at fault here, IMHO. I think its the related
components that are the problem. It sounds like the hot/warm start
problem could be caused by the fuel accumulator is my first guess. Theres
alot to check on the fuel system. Id say your just gonna have to check
each item and rule them all out before doing anything drastic like an
engine tear down.
Check all the electrical connections, make sure they're good ect. Check
for good grounds ect. 

Mike told me to replace my Knock sensor on my GLi because the wire was a
little frayed. He said if they are damaged at all they dont perform like
they should. So if the knock sensor wire is frayed or damaged even a
little bit, it might be a good idea to replace it. (I did.)
HTH!!
