Sounds like a "surging" issue, USUALLY the carburetor, best thing is to THOROUGHLY clean the fuel tank, replace the fuel lines, filter and shut-off valve (if so equipped) THEN do a carb cleaning making sure it's REALLY clean ( all the passages) a carb O/H, or even a replacement carb, if carb is deteriorated .
