Right after we had the hard freeze here back in February, the pump started getting louder. I'm guessing that maybe there was moisture in the tank/pump that froze and screwed things up? I've been keeping my trips short with the truck, 'just in case' since then and it died in my driveway.
It does have an external filter. I replaced it last summer, then again for giggles when the pump started getting louder.
