RXJS BehaviorSubject when using ion-menu

Currently I have my app component with an ion menu component inside of it. There are 2 ion-list components that load two additional components. I have stateful information that I want to set on an injected service that will be accessible from a subscriber in the other component. Currently I can not get this working, it seems that the components are destroyed each time I navigate to the other page. I need some way to keep stateful information between components, any ideas?
