My peaches have developed a problem where the peaches seem to be releasing a sap and the leaves are sticking to the peaches and rotting them out. What can I do to stop/fix this?

This is not actually sap, but honeydew from a pest infestation. It is likely aphids or scale. Treat the tree with an insecticide. I like neem oil myself. It is organic, safe for people and pets and also treats other undiagnosed problems the tree may have.
