Premature Dropping of Vegetable Flowers

As with squash plants, this is typical behavior. They will produce mostly male (non-fruiting) blossoms early in the season (which normally fall off) and will gradually start to produce more female blossoms as the season progresses. Give it some time and you will see it start fruiting.
