I got an erroneous indication on the cockpit display then a complete loss of GPS signal. After several attempts to regain a signal and be able to navigate to the next Waypoint; I had to ask Center for a heading till I sorted out the issues. Finally after several minutes I was able to get a distance Waypoint and able to navigate to that intersection and no further issues happened. This happened near the area of Restricted airspace R-ZZZZ past ZZZ1. Looking back; I'm convinced my GPS signal was jammed by the military.
BE90 Pilot reported indication of temporary loss of GPS signal near restricted area and stated it was due to GPS jamming.
