Narrative:
Departed runway 28R on SID departure from pbi. I was flying with FMS navigation selected. Prior to FIX1 intersection; the flight director and autopilot disengaged. The right eadi [electronic attitude direction indicator] and ehsi [electronic horizontal situation indicator] showed a turn; while the left eadi and ehsi indicated climbing straight ahead toward FIX1. Passing FIX1 I continued straight ahead when I should have turned right to the next fix. Departure asked if we were turning right to the next fix. The first officer quickly requested a right turn and stated we had encountered a navigation problem. Departure gave us right turn heading 360 degrees with a climb. During climb the right eadi and ehsi returned to normal and we so advised departure(they did not indicate any problems). Flight continued normally to destination.
