So if you intend to go flying and taxi to the gas pump only to find they are
out of fuel, then taxi back to the hangar - you can log the time to the pump

Nope. You taxied to the fuel pumps with the intention of fueling the aircraft.
Once at the pumps, you shut down. End of cycle. Next engine start you go from
the fuel pumps to the runway (with the intention of flying), and that taxi time
would count.
