Re: Intermittent power loss (need help troubleshooting please)

Have you replaced the gas cap lately by any chance? If it runs for a while before becoming sluggish it could be creating a vacuum in the tank. I know someone earlier mentioned taking the cap off to see what happens but not sure if that was tried.

The sock filter on the end of the pickup tube in the tank would be at the top of my list of things to check, as would be a plugged fuel line from tank to pump. Here are pictures of a plugged sock filter and pieces of a filter that were plugging up a fuel line.
