Aircraft
Approaching DC SFRA I experienced intermittent electrical failure. During this time; GPS Navigation devices were inop. I restored power; however; comms were unreliable. Attempted to contact Potomac Approach on 132.77; but was unsuccessful.   During this time I inadvertently entered the DC SFRA for a few seconds. After exiting; Potomac Approach contacted me and informed me that I had entered the SFRA. In cockpit; distractions were the cause of the unintentional flight into the airspace.
RV-8 pilot reported an electrical power interruption resulting in GPS failure and an airspace violation.
