Angular2 Lazy loading Fails with a shared module

I've created an AccountModule that successfully lazy loads, but when I add my SharedModule to the AccountModule my app seems to forget all of my eagerly loaded modules and I get the error:

Component FoodComponent is not part of any NgModule or the module has not been imported into your module.

Where FoodComponent is an eagerly loaded component that both loaded and rendered correctly before calling for the AccountModule via lazy load. If I remove that component fro the app, then the next eagerly loaded component send the same issue. What is it about my SharedModule that is making this happen?

shared.module.ts

// ... imports ...

@NgModule({
  imports: [
    CommonModule,
    MaterialModule.forRoot(),
    ReactiveFormsModule,
    AppRoutingModule
  ],
  declarations: [     
    CalNavComponent, 
    IngredientsListComponent, 
  ],
  exports: [ 
    MaterialModule, 
    ReactiveFormsModule, 
    CommonModule, 
    AppRoutingModule,

    CalNavComponent, 
    IngredientsListComponent, 
  ],
  providers: [ 
    UserDataService 
  ],
})
export class SharedModule { }

account.module.ts

// ... imports ...

const routerConfig: Routes = [{
  path: '',
  component: AccountComponent
}]

@NgModule({
  imports: [
    SharedModule, /* Works fine when this is gone */
    RouterModule.forChild(routerConfig)
  ],
  declarations: [ 
    AccountComponent
  ],
  exports:[
    AccountComponent
  ]
})
export class AccountModule { } // adding 'default' results in "cannot find module at app/features/account/account.module"

app-routing.module.ts

const routes: Routes = [
  {
    path: '',
    redirectTo: 'food', 
    pathMatch: 'full'
  },
  { 
    path: 'account',
    loadChildren: 'app/features/account/account.module#AccountModule'
    // component: AccountComponent, /* This worked fine*/
  },
  {
    path: 'food',
    component: FoodComponent
  },
  //... more paths
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})

export class AppRoutingModule {
  constructor() { }
}
