If the pedal gets hard, it sounds like you are losing vacuum to the booster somehow. If the shoes were getting hot and fading, the pedal would still feel the same and you would likely smell the hot brakes.

Is it possible the vacuum hose to the booster is collapsing when it gets warm? Is it the correct type of hose (i.e., vacuum hose and not a piece of fuel hose)?
