Am a looking at a fuel volume issue?

The other day coming home, my truck lost all power to the point that I had to pull over and nurse it up a hill. I drove acouple more miles, stopped for gas, then continued home-and it seemed to work fine.Til the next day, the problem has come back and has not left. I've changed the maf, o2, tps, distributor, and ran all diagnostic modes. The modes came out at a 55, no mal.I put my fuel pressure tester on yesterday, and at idle it was barely 31psi, and with the vaccum line disconnected, it was just pushing 40psi.

I also took the fuel line off at the rain and let the gas pour into a container, and it seemed to work to get the fuel to come out. I tried just cycling the key, and starting it. Should the fuel not just pour out of the line when the pump is energized? Because like I said, it worked to even push out not even a quarter of a quart.

Thanks

Fuel pressure regulator may be bad

Fuel pump issue or a plugged sock it sounds like.

I'm thinking fuel pump myself. Does anyone know what our pumps should flow into a container with the fuel line disconnected in say a 30 sec time frame?
