    just an idea but my old vq would do the same with starting,when cold was fine but after driving it,it would act like the battery was going flat/was hard to start. turned out the solenoid in the starter was buggered.
    put a new one in and was all good after that.

    Harry, start with the basics.

    Start with your Starter motor; and work your way around from there.. With the fuel problem; check your Fuel Pump, lines, filter and pressure regulator.

    Best of luck.
