Sounds to me like you have a sticking brake. A thorough brake inspection would be in order at a shop and You can locate places that inspect them for free.
A seized caliper or a stuck brake shoe would cause the symptoms you report. When stuck it will not allow wheel to turn. When enough force is applied (via the drive line) it releases with a sudden surge of power breaking the traction of the tire.
