My 1994 gmc Yukon completely shut down after hitting a pot hole. Won't do anything nothing works. What could it be?

Looks like it lost battery power. Check around the battery for loose or broken connections at both ends of the battery cables. There's one from the battery minus to the engine that could have broken.
Hope this helps.
