Growing season - replant when cooler?

I'm working on my first in-ground crop of tomatoes. Got a few nice ones this year but should have pruned early because the plants got to be huge with few fruit. We're in 100+ temps right now. Two of my three plants are flowering and I'm watching to see if they set fruit. IF they don't should I cut them back and see if they'll return in the cooler temps this fall or dig them out and replant at the end of the hot summer?
