Hello Thomas,
There are a number of different diseases that can cause the leaves to die and fall off elms. I recommend sending a live sample to the U of MN Extension Plant Disease clinic for a diagnosis. Here is a link to their website where you'll learn about their services, prices, and how to submit a sample. I also recommend contacting them by phone (number's on the website) to have them assist you in determining what is a suitable live sample so that time is not wasted sending in the wrong material. They are very helpful.
