Really now? Do you think the plants will grow big enough if it's giving all that energy to the buds/peppers?
In my experience, unless you're artificially stimulating the plants to bear fruit with high-number ferts, they abort if the conditions aren't right/they're not ready -- if they're shocked at transplant, for example. Even if they keep the flowers/fruits, if they decide to concentrate on growing roots and leaves, the flowers or the baby fruits will just remain small until the plants can turn their attention to them.
ETA: Also, when I first plant the peppers, the temperatures are not the optimum for fruit production, unlike the warm indoor conditions under the lights -- which, I suspect, also makes the plants have second thoughts about developing the baby fruits.
