RED "X"s ALL ADHARS/EMS/MAP 3 finger Reset Needed

[skypilotusa]

I am about 3 weeks away from getting my RV-7A inspected for flight.  I have (1) 10" Skyview, EMS, ADHARS, Xpndr.  They have been installed and tested for about a year now.  Just in the past 2 weeks during testing of the systems... I sometimes get 3 RED "X"s across all systems, ADHARS "X" / EMS "X", MAP "X" all at the same time.  I can do a 3 finger reset and may not see it again... Today during testing all systems I had to reset the skyview 3 times. 

Also, when I was in the setup menus the Skyview locked up and stopped responding to any input. Another 3 figure reset required.

Any Ideas?

Maybe it is a loose connection somewhere in the wiring. Does it happen when there is movement of the aircraft or can the system stay on when left alone? :-?

Happens standing still in the hanger... The Skyview has "NOT" went offline with the engine running and aircraft moving, at least yet. I have 2 engine runs, run-in, and full static rpm checks. with about .8 hrs on the engine at this time. Everything else in the aircraft (Electrically) is rock solid. Running VP-X Pro, Planepower 60amp main, and Planepower 30amp Secondary ALTs... Dual EMag-P114.

I Also had 3 crosses appearing but only for a few seconds it was caused by a wire to the gps aerial rubbing on the choke cable and sometimes shorting to earth

Does it happen frequently enough that you might be able to get a video of it and mail it to us?

Yes... I will see what I can capture. Boot is normal, everything seems to be working fine. Then "Splat" everything goes offline. I thought it may be a low battery, but I ruled that out the other day. Main Battery showing 12.5v. It seemed to start when I installed version 7 about 6 months ago... But that is just a guess... Since the plane was not being powered up much back then I forgot about it. But, in the last month with Engine Starts and system testing it is happening almost daily. Seems strange that ALL systems would go offline. anyway... I will see what I can capture.

I was able to capture the failures in a video this morning... Where would you like me to sent it? The ADHARS/EMS indicated failure after the system was powered on for about 12 minutes...
