    Either the genset (?) Cannot power the pump, or the pump takes a lot of current to start (bad starting capacitor  low genset voltage, etc.).

    Try wiring to the genset directly. Long wire runs with too much voltage drop?

    With the generator un-wired, probe the connection points and verify you actually have 240V there and not 120V

    What other loads are applied to the generator?  A battery charger for example could be drawing a significant amount of current, but without details, one can only speculate.
