RV issues - DirecTV

I have a receiver in my RV along with a Winegard dish. Things have been fine but since Thursday at 2 different stops, I receive a 771 error message. It started on a few channels and now appears on all channels. I've also noticed my guide is showing the time in CDT even though I'm in PDT zone. Any ideas?
