Mercury 40HP 4 cylinder 1995

Same issues as others I have read. Engine idles fine, but when I go to 1/2 to full throttle engine goes well for 30 seconds and then bogs down and then goes intermittent up and down, but never restores to full power...unless I move throttle way down for 30 seconds, then it will go full throttle again for 30 seconds or so, then bog down again. New gas line 2 years ago, non oxy gas, and have already spent $1k three years ago to solve this issue, now it is back.
