Hi Joseph
It sounds like you're dealing with some squash vine borers. They are a common pest on pumpkins and other squash/cucurbits species in MN. There's one generation per year that emerges from cocoons within the soil to destroy our gardens. As far as the best ways to keep them from attacking your pumpkins there is a few methods. I think rotating planting locations and using floating row covers could work well. I will attach a few links with information about preventing them.

And here is a link with information about harvesting and storing them.

I hope this helps you keep some pumpkins going this year and into the future!!!
If you have any other questions or concerns feel free to reach out to me or the extension.
