I was returning to port last night when my instrument panel went out. Fuel guage, starter, speedometer and tacometer were all working but the rest of the panel was gone. I had no navigation lights, anchor lights, docking lights, Bilge pUmp, etc..... After about fifteen minutes some things would return for a short period of time before quitting again. Does anyone know what the problem may be or how to troubleshoot this.<br /><br />Thank You
