Indeed, it does sound as though fuel pressure is not being maintained at the rail...hence the continuous cranking. Once left sat for a time my first port of call would be to check there is fuel pressure at the rail (goggles at the ready - press the Schrader valve) and then check the Fuel Pressure Regulator on the other end of the rail. You can remove the vacuum line to the FPR and if fuel comes out the diaphragm is damaged.

If you have passengers on board and it fails to start again in the meantime try priming the fuel pump 3 or 4 times to bring fuel to the rail before trying to start.
