Heat & Fruit Drop

Howdy. Where I live has been experiencing temps of 90+ for the last week or more, with no sign of cooling down… My peppers have been doing great, for the most part, but one of my plants refuses to hold on to any fruit. I have 2 other plants of the same variety that started flowering earlier than the plant in question and are currently loaded with peppers and still producing, while the other plant is loaded with flowers. As soon as the flower turns into a pepper the size of a BB they drop. Is there anything I can do to encourage this plant to hang on to its fruit? I have moved it into the shade in hopes that this will give it the reprieve from the heat that it needs to start producing. The plant is huge and otherwise healthy, it kills me to see all of these potential peppers dropping. Any tips would be much appreciated! Pepper pics just because. Thanks.
