I went out there and fiddled with it and it's back. I can't imagine what bumped the dish off... that bad boy was locked down tight. Wanted to see before I did that if it was just me. Thanks all.
If you start seeing problems at different times of the day and/or after viewing for a few hours, its the LNB. I had mine go out once already. It would work in the cool mornings, but not in the hot evenings.
