Things that need checked.--- LNB might be going bad. Problem with cable from receiver to LNB. Constant voltage at LNB should be 13-19 volts. If fluctuation in voltage, check all exterior 'connectors'. Unscrew to see if copper wire is good. Any cuts or abrasions to the co-ax cable.
Does the dish have a clear view. What ever your elevation setting, look up an additional 12-15 degrees. [where the sats are actually located] Any hanging tree branches that have grown.
