Home electric circuit goes dead without tripping breaker
I would be verifying that all 8 outlets are not working, this is quite common with backstab outlets that are daisy chained. The problem is usually found at the first non working outlet or the last working outlet. This failure is much more common than a circuit breaker failure. The open circuit condition can be on the black or white wire, if it starts working after pulling the outlet and back stabs were used the outlet should be at a minimum rewired to the screw terminals or replace the outlet with a spec grade 4$ vs a .98$ outlet , but verify the working / non working outlets. 
There is a slight possibility of a bad panel with FPR or federal pacific stab lock breakers or a zinsco these are known to have issues and are beyond the average home owner repair, verify all the outlets first next time it goes out.
