Bud,
I am having the SAME problem up here in PA...and it is fairly recent, just like your issue.
I have a thread going below, in the ADSB section under "Rebooting in Flight" to address this.
So far no one seems to know. I have even photogrpahed the images and posted them for analysis - so far, no explaination.
About the only thing I get back is "Re-flash the chip." I am not so sure that is the answer....what is the problem?
Something has changed....just not sure what, but my ADSB Stratux is simply not nearly as reliable as it was before.
Mike
