Could you be over-watering them?

Ok, I'm struggling to remember my botany from <mumble> years 
ago,  but in really hot weather a plant will sometimes transpire 
faster then its roots can take up water. The water pressure in the
leaves drop, giving it a wilted look, and the stomas close, thus 
preventing more water lose. 

 The impulse is to water the plant because it looks wilted, but
it doesn't necessarily need watering.  As soon as the conditions 
(usually heat, but sometimes wind) that are causing the rapid 
transpiration are changed, the leaves perk right up. 

 Try checking the soil before watering. If it's moist, don't
water. This is especially true if your containers have those
little water catchers under them to hold water. Peppers, in
my experience, don't like to have their feet wet.  Remember 
too, a little heat stress can make for hotter peppers.
