Q.My Cucumbers Start Vigorous Then Gradually Die Off When It’s Time To Produce
This seems to be a problem with all vine-type vegetables for me (melons, cukes, etc) This has happened now for about 4 years in a row. All other crops do well (tomatoes, beans, peas, etc) I try to rotate where I plant every year, have been gardening in this place for 15 years now. Prior to 4 years ago, I had wonderful cukes.

Unfortunately, without photos it can be hard to diagnose what is going on. To me, it sounds like Cucumber Mosaic Virus, and that your other crops are resistant to it. Some cultivars are more resistant than others, but cucumbers are very susceptible to it.
The alternative is that some of your other plants are only mildly affected, and the damage is not noticeable.
