Has anyone ever had any issues with random inflight failures of their GTX 345? This has been going on for the past few months. It does appear random as we wont have any issues for a while and then it happens again. I attached a picture of the initial message. The only way to get it working is to power cycle the transponder. Pressing ALT or anything else doesn't help. It does show a message on the messages page that says "1090ES ADS-B OUT FAILED"
