Could be a fuel issue. I would start with a warm compression test, then inspect all your fuel lines. Old mercury fuel lines are know for delaminating from the inside out, So be thorow.

My 60 4stroke fuel inj had similar problem-fuel lines bad on
inside,replaced and also found the mechanical fuel pump to
be unable to provide sufficient fuel under load-replaced pump
and problem solved.
