Are they producing male or female flowers, or are the baby cumbers just drying out and dieing ?

Even if there are male and female flowers but a lack of pollinators you won't get cukes.  Have a look at the vines in bright sunshine and see what sort of bee traffic there is.  Remember in wet, gloomy weather bees stay in the hive.  As a last resort you might need to hand-pollenate but it is a lot of mucking about.
