Default 1984 Starting Weirdness

I have a 1984 GL Wagon that is displaying some confusing behavior. It won't start after sitting for a day or so. It cranks fine, there is spark and compression. The exhaust does not smell of gas. So I pulled the gas line off of the white cyclinder with 3 attachmented hoses (what looks like a fuel filter) and confirmed that gas was being pumped by collecting gas while the car was cranked. Now the weirdness. I hooked the line up and it started up and ran fine. I drove it for roughly 10 miles, stopped and started. However after sitting overnight. No start. Removing the line, cranking and collecting gas again. The car starts. So I think there is a fuel delivery problem. But I'm baffled, what could be happening during the roughly 24 hours of non-operation that would disrupt the fuel flow, and why would opening the fuel system, running the pump and reconnecting fix it?
Since it is below freezing outdoors where the car is I would appreciate any suggestions.
Thanks in advance.

It may have another fuel filter, located at the fuel pump. Thats right in front of the right rear passengers tire on a metal platform. It could also be the fuel pump going out, but I would start with the filter first.

I replaced the underhood filter and it seemed to be fixed. We had the first real snow of the season, and the problem reoccurred. I pulled the hose from the new underhood filter and cranked the car. No gas, so I agree it is either the pump, under car filter or a plugged line. I suspect it is the pump because it has been a bit slower to fire the last couple of times I started it. Not much, just 2 or 3 revs more. That seems consistent with a progressive pump failure.

NAPA should be getting the replacement filter and pump today, so we will see. With the snow both of my 4WD vehicles crapped out. The alternator in my 83 beater truck failed while my wife was using it to motor through some lousy conditions. I must be getting old, working on cars in sub-zero weather is not as much fun as it used to be.
