    Check you fuel supply lines. If not they are ethanol compatable they can deteriorate and cause fuel restriction and blockage.

    In addition to this, make sure your fuel tank vent hoses are clear and then you might have to pull the pickups out of the tank to make sure the check valve is ok on them.

    Fuel restriction?

    I've seen some fuel hoses collapse from the inside and restrict fuel flow. Might want to swap hoses or replace 1 to see if it helps. Also we had one boat where a clamp was crushed on a hose and crimped it nearly shut. Check the fuel lines carefully.

    I know this is response is a bit late.

    but check the fuel pumps.

    I had a similar issue on the same boat after a long winter storage, when the boat got winterized by a yard.

    Both pumps on the 454s went bad at the same time.

    To this day im not sure why, I can only guess and blame it on Ethanol.
