Dumb question but are they dying from powdery mildew but meanwhile your acorn squash are resistant or the soil where you have them is better?
Granted I just ate my first immature 2" diameter scallop zucchini (yellow spaceship) off the vine and it's mid August, but I am growing on compost and on non insecticide hay bales beside a compost infill and both are working for me, the squash on the nettle hill topped with nettle stems and a bit of soil are doing best and of course full sun. Those plants were seeded outdoors and transplanted into clumps into flats to protect them from wildlife then planted once secondary leaves were established
Another possibility to consider would be mosaic virus
I'm the past I did Lebanese cucumbers where I had contaminated soil in a community garden.
You may know all about these scourges of the squash and cucumber family but I figured since others are reading as well I would ask the obvious question since your aunt can grow them but you can't and she will have a different location so maybe it's the soil (so straw bales may help you, but will need lots of watering)
PS
I have had problems with imported soil from purchased seedlings and powdery mildew in that soil in the past, but with caution in advance and elimination I am powdery mildew free!! (Pot into really old brittle buckets and keep them downwind then watch them; break the buckets and plant on hills if by the time they are outgrowing their buckets they are free of problems)
Now I won't buy any seedlings and of course you're planting from seed so not bringing in contaminants.
And I have been struggling with potatoes
