Cherry and pear tree
Both of our cherry trees and pear tree look like they have died. They started out with the leaves turning brown and then the branches. The trees are about 3 years old and were doing great until this. Is this the cause of a bug or lack of something? Can we cut the trees back and see if they will come back out? Is there something we can feed or spray them with that will help them not die.

You have provided very little information to make a good assessment of the situation. Are there cankers (dead areas on the trunk) on any of the trees? Did the trees leaf out and then die? Were they planted properly? How have they been irrigated, both frequency and duration?
Both cherry and pear are susceptible to a disease called bacterial canker. This disease can and often does kill entire trees. This is the first thing that comes to my mind as a possibility. If the trees are infected with bacterial canker it probably won't help to simply cut them back as the bacterial moves systemically in the tree. Here is more information about this disease. http://pnwhandbooks.org/plantdisease/cherry-prunus-spp-bacterial-canker
