Set 500' I'll bet there is more than one check valve in the drop pipe. But a hole between two check valves usually causes air to blow a glass out of your hand at the sink? A low producing well usually makes good water for a short time before dropping off. Could be either the water level is deeper than your pump can lift or the pump is wearing out. Either way your problem is that the pump cannot build to 60 where the pressure switch can shut it off.
Nothing odd at the faucet. Everything seems normal there. No air or extra debris.
Oh I wonder if water isn't flowing into the well much right now for some reason. That could explain why it takes a while for it to get back to 60psi.
