Is there a check valve in the power steering/brake boost pump that can stick?

Went to leave this morning and no brakes or steering. Shut it back down, checked fluid level and it was full to top. Started back up again and revved it a little and all was well.

Are there any known problems to be looking for? Only has 66k on it 2006 K3500.

Would not be fun to have it happen while driving. . . . .
