Any ideas,folks?This started this week after a record setting July where 100 degrees was the norm.
It`s down to the low ninties now.

I'm not an expert, but it looks just like the bacterial wilt the cucumber beetles carry. Have you seen many of those beetles? Small, yellow and black striped or spotted?

That seems pretty extreme for sunscald, especially in this family of veggies. They're not reviving with the milder temps, or with water?

Edited to add: you'd see the beetles actually in the blossoms.

Have you checked the stems for the squash vine borer? Cucumbers are usually not attacked, but that doesn't mean that they are never attacked...And wilting and die off are symptoms.

It looks like some type of wilt to me. Could be bacterial, viral or fungal.
How to the stems look at the point of wilt? Do you see any insect activity at the base of the stems? You may want to cut a few of the stems open at the point of wilt to see if there are any larvae hiding in there, or see if you notice anything else about the stems condition that you help you identify the cause.

I have had vine borers attack cucumbers especially burpless variates I think the stalks are softer check the base of the plants from the ground to about a foot up .
