Debris in a fuel sock can come and go. When the pump is working it sucks and holds debris in the filter. When it's off, the debris can settle back into the fuel tank. It will be interesting to see if you find debris in the tank or sock. If the sock filter gets partly clogged, it could explain the difficulty on the hill when the most power (and thus, gas) is needed.
