My plants look healthy and are flowering nicely. The problem is that the flowers when they mature are falling off and I see no sign of fruit/squash growing.

Squash plants produce male flowers first.The blossom drop that you see is probably the male flower, which is supposed to dry up and fall off. Only the female bloom produces fruit. The male stem is thin, while the female stem has a swelling behind the flower; that is where the fruit will grow. All squash plants have both male and female flowers.
