Louie Luchini and Ben Fletcher ran 4x800, 1600, 800 and 3200 quads in 1998 in the Maine B and A meets respectively, winning all four. Unfortunately, there is no all-class meet in Maine. I highly doubt either of them could have swept the other in all four in one day.
The Taye brothers could have but for each other last year. Sintayehu ran 1:54 (relay), 4:13, 9:11 and 4x400 last year.
