Fuel Pump Issue?

Also, there is a chance you have the little disk about the size of a dime / nickel of a paper type plastic floating around the tank. Ever so often it is getting sucked up and shuts off the pick up tube. Those disks come from “dry gas” or other fuel additives. It’s a sealing disk to make sure the bottles don’t leak. Sometimes they fall in the tank and cause all kinds of issues. Not all tanks have socks or the socks broke up and that is an issues since it is a plastic like filter.

“IF” this is your issue then the tank has to come out and be dried out and then blown out until the part / pieces are gone. Typically thru the sending unit hole.

I’ve not seen this be an issue in a long time. But it is a possibility.
Good luck
