I have multiple tomato plants that are flourishing and 2 that are covered with blooms but no fruit. I understand the hot/cold, sunlight and water issues but cannot figure out why so many are covered with fruit and these 2 are hold outs. Can you give any insight?

You may be having an issue with excess nitrogen in the soil. Too much nitrogen or over fertilizing can give you nice lush plants but not flowering or little flowering.
A soil test can answer this question, but that can take a few days, I would apply some phosphorous to the soil. Phosphorous will promote flowering. Bone Meal is a great organic method to do this.
Here are some links with more information.
Also, you local County Extension Office can help you with a soil test for a small fee.
