Squash plants are getting holes in leaves like an insect is attacking it. Squash plants just seem to be dying.
You can try some insecticidal soap, it's possible you're dealing with flea beetles which riddle the leaves with holes. Also see this article for more info:

What type of squash has a maple leaf type?
Yes, the leaves have serrated edge, and vary in size and shape, but typically have 3 to 5 lobes and are rather large in size.
My zucchini (and this year I added summer squash) dried up and died after a good start. The tomatoes next to them are fine. Do you know why? Also, beetles on the roses are very persistant. What works best for that?
Do you live where the weather is hot? Squash like cooler temps. Mine die out about this time of year. Also, have you seen any sign of squash borers? Tomatoes are ripening right now in my garden, and Jap Beetles are eating my roses, too. I keep a bottle of spray made up and go out every day and if I find them, they get sprayed. Also, you can take a bucket of soapy water with you and just knock them into the bucket and they will drown. Hope this helps. Luciee
I have green bugs and white smaller bugs that look to me like stink bugs. They hover over my squash waiting for a meal on the leaves. Are these problems for the plant and fruit? And how can I repel these while keeping the beneficial bug balance? I have an organic garden for sustainable agriculture.
Most of the time they are not harmful, but they can carry diseases that can hurt the plant. I like to use neem oil for organic pest control. It is safe for people, pets and beneficial bugs but very effective on bugs that feed on plants. Here is more information:

The squash and zucchini plants in my raised bed seem to be too crowded and overwhelming each other (and the carrots). How do I thin these out without damaging them and maintaining quality production vs quantity? I did not trellis this year and am regretting it!
Uproot some of the weaker plants with their vines and leave the strongest ones. Next year, thin when they are still seedlings. I know, thinning is one of the hardest things for a gardener to do, but you're doing your plants no favors if you don't. By thinning early, you allow the one's left to grow into stronger, healthier plants. The one's thinned out leave air pockets for more light and water to penetrate the soil and help the others in that way. Just water well when you are done thinning, the others should do just fine.
I have 3 different kinds of squash growing in my garden. The plants are big and beautiful; however, the squash starts to grow great and then all of a sudden it begins to rot on the stem. Why is this happening?
It sounds like a pollination issue. These articles will help you:
