** Most likely it is that receptacle, specially if plugs are loose in the receptacle or the connections at that receptacle. **
In such a case also check the plug on the cord that was plugged into it. If they show signs of arcing (discoloration, pitting, etc.) or melting, it should be replaced before plugging into another outlet.
BTW such signs would be a good indicator of an outlet problem.
