I mowed about 3 hrs and it died. Would start but die immediately. Found a clogged fuel line, blew it out, and it clogged again past the fuel pump. Blew it out and fuel flowed all the way to carb. Started it and it died again immediately. Would it do this if fuel pump is bad? I drained and put new fuel in so it isn't a fuel issue. The filter looks fine and fuel is abundant past it but seems limited past the pump though
