What you just described sounds like you might have a cracked line between the water tank and the water pump. And it sounds like the cracked line is that portion of pipe that is inside the water tank.

If the "outbound" hose is cracked (long ways), it sounds like the crack is completely covered with water when the tank completely full. Therefore, there is no way possible for air to enter the system.

As you use the water out of the tank, the water level lowers. Once it lowers to where the crack starts, your pump is not only pulling water, but also pulling air and thus, the longer cycle times.

As the water drops even lower, the crack is allowing more air into the lines, until finally, when the water reac hes a certain point at a low level, the pump is actually pumping more air than water, and thus, loosing it's prime.

From what you described above, your water line is cra ked. The cracked line in that portion of line inside the tank.

The end of that pipe should be almost touching the bottom of the lowest point in the tank. So, there's probably 8 inches to 12 inches of hose inside the tank, depending on how thick the frame of your trailer is.

This is what it sounds like to me, after your description above.
