My biggest problem has been growing crookneck squash. I don’t know if it’s pest related, but my plants always die. Every year they start out big and healthy, then they bloom like crazy and put on squash, then they seem to die overnight.
That’s terrible. How disappointing.
Could be squash vine borer.
They lay eggs at the base of the plant and chew into the vine and then the plant seems to die overnight.
The first thing that jumped to mind was squash borers. From the article I’m linking below:
“It’s an all too common occurrence. Your squash plants looked fine yesterday. Today they’re wilting, and no amount of watering has helped. What happened? “

Good luck!
Sounds like squash vine borer. Happened to me last year. Moschata varieties are more resistant, growing one this year called Zucchetta Tromboncino, dual summer/winter squash, also have had good luck with Tetsukobuto, a moschata x maxima hybrid. Both available Pinetree.
Seminole squash said to be very resistant, very long vines, climbs trees, long growing season.
Get chewing tobacco and soak it in water. Pour the water on the ground where the squash will go. Nicotine is deadly.
