Hints like bloom pix, time of bloom and pix of a leaf on a white sheet of paper (with a quarter on the page to provide size reference all help. A picture like what you provided gives little information.

Re: Tree Identification & Wilting Prevention
From the closeups, it looks to me like it might be an apple or crabapple tree. I think that looks like lichen in the last picture. I don't think lichen is harmful to trees, but I could be wrong.
I don't really have an answer to why the leaves wilted and fell off. How often did you water it last year? Was last year especially wet or dry? What's your soil like? Do you know if the leaves fell off that way for the prior owners?

Re: Tree Identification & Wilting Prevention
I was certain that it was a crabapple but figured I'd wait for closeups to confirm. It's definitely a crabapple. The lichen is not parasitic and will not harm the tree.
The most common diseases of crabapples are scab, fire blight, cedar-apple rust, and powdery mildew. The disease most responsible for defoliation is cedar-apple rust. Your tree looks fantastic this year, so it's hard to imagine that it succumb to heavy enough rust pressure last year to cause complete defoliation, which usually results in sparse leaves and flowering the following years. The yellow/orange spotting of leaves is unmistakable with cedar-apple rust.
Read up on cedar-apple rust and fire blight. ID what you have based on you what you observed last year. I refer to the VT Pest Management Guide: Home Grounds and Animals on such matters, particularly fungicide and pesticide choices and schedules for fruit trees. I spray apples, crabapples, and hawthorns with Immunox (myclobutanil) to prevent cedar-apple rust, which is rampant in this area. The infection happens well before visible symptoms, so it must be applied multiple times early.
