Crosscountry travel with AP engaged. GPS mode reverts to HDG. After a few minutes position lost message. Finally self restores after 18 minutes. Data log shows zero satellites available during this occurence. BUT, iN the meantime, my modest Garmin aera shows availability of at least 9 satellites Among 5 green. Showing on attached picture. This happened to me on 2 different Shark UL numbers fully HDX equipped. Thanks for quick help.
