Recently we were coming home from Florida in bad weather and had to stop for the night. All lines were full from city water the prior week, however when I started the pump to use the FW tank, tons of air. The pump would not shut off as it could not make pressure due to all the air. When we got home I drained and refilled the FW tank, drained all lines, and started up the pump again. No problems.
I have come down to two possible explanations:
1) some type of hyrdro-lock. The fact that the pump was dry and therefore had air in it, but the lines were full from city water, created a hyrdo-lock situation where back pressure in the lines was greater than what the pump could push through. Generally, the lines are dry as well when you first start the pump.
2) it was cold enough that the water pressure in the lines was greater than usual and caused a blockage the pump could not move.
My advice is drain your lines at the low point drain and basically start from scratch.
Also note - if the hot water heater is open and has air in it, it takes FOREVER to move all that air out.
