If you're getting tired diving, being fitter will help, but diving more efficiently is a good start too.
I've seen studies that suggest muscle endurance is actually quite motion-specific - Lance Armstrong called running a marathon the hardest thing he'd ever done despite being ridiculously biking-fit and training hard for running. So if your legs get tired when diving, I suggest swimming (especially with your fins on) without using your hands.
Whatever you do will help, if only by making you more efficient at using air, but if you want to swim longer, faster, easier, then the best thing to do is to swim.
