Need advice: GPS175 intermittently loosing pressure altitude, heading and ADS-B traffic.

I’ve recently installed a new dual G3X IFR panel with a GPS175. Strangely, everything performs well at start-up, including the Bluetooth traffic from the 175 to my iPad with FF. However, during each flight, I will get an error message on the 175 that it had lost pressure altitude and heading source and the traffic drops off as well (both on the 175 display and Bluetooth). I’ve confirmed the configuration settings (which should be correct given everything performs correctly on the ground), but can’t figure out why I keep getting the error messages and loosing traffic on the 175. As a sidenote, traffic continues to be displayed on the G3X even when it drops off the 175.

Any advice as to what may be the problem would be greatly appreciated.

Many thanks, Mike
