@Pat_17 I have satellite and rarely have drop out bad thunder storm heavy rain.Have you reset your receiver? Have you gone to menu and checked your signal strength. Right now mine is 100%. If it is low possible with winds could knock it out of alignment. Phone in and get the satellite people to check your receiver from their end. You might have to get it realigned or receiver replaced.
As @polecat suggest, those are classic signs of weak signal strength. Your dish will need to be re-aligned for max possible signal strength.
