I've got a squash plant that is growing pretty well, and it has some
pattapan squash fruit on it. I've noticed that during the part of the
day that it gets the full hot sun that it wilts back, but when it gets
the afternoon shade it perks back up again. I haven't seen any borer
holes in the vine stems, either, and I've sprayed it with BT in case
some worms do get to munching on it.

Is it normal for squash plants to wilt like that during the hot part
of the day? It doesn't lack for being watered, either.

Yes, the leaf area can be too big for the water transport ability of the
roots and stems even without borer damage when it is hot. You might improve
it by mulching as this will slow the top of the soil drying out between
watering.
