It could also be that your plants are getting too much nitrogen and not enough other nutrients.
My plants (various types) are between 4'-9' tall, and all are producing quite a few tomatoes (some are absolutely loaded). But I also ran into the problem of losing blossoms when the heat was raging a few weeks ago (and like it is today!) - there's just nothing you can do about that. But as long as it's under 90 or so, then the blossoms generally set fruit.
I only fertilize with compost tea brewed with fish fertilizer, so I get plenty of other nutrients besides nitrogen.
