That was the only time I have ever had trouble with cool power fuel. So don't hesitate to try a different fuel. It might do the trick for you.
When I read that Cool Power was being used, I started to think along these lines, too.
For the short term, I suggest that the OP run his engine a few clicks more rich. When that gallon of fuel runs out, I suggest that he change to something else. I changed from Cool Power to Omega. The difference was amazing.
