I have an IFD 440 on V 10.2.2.0.A. About 1 hour into each flight, the unit loses all GPS and goes into dead reckoning, which typically coincides with a status switch from GPS to GPS-> VLOC. If I cycle the unit OFF/ON, it will typically regain GPS-contact, at least initially. My main unit is an IFD550, and the IFD440 is on cross-fill.

Any idea?
