NatGeo HD is on TP30 of the 129 satellite. This sat is one of the most troublesome ones they have in the fleet and has signal strength issues. It is at the end of its life cycle and is in the process of being replaced, hopefully the new sat will arrive in proper orbit and channels will be coming from it within the next month. Hopefully that will help your issues.
For reference, other HD channels on TP30 are
NHLNet, FoodNetwork, HGTV, ESPN2, NFLNet
So check and see if you have issues on those channels, which if it is a signal dropout issue you should.
