About once a week - When I start my 2012 GLK 350 it won’t start . I wait 5 minutes & then it starts.

It could be a faulty fuel pump. An actual mechanic with hands on could tell you for sure.

What do you mean by “won’t start”?

You try to start it and the starter turns the engine but it won’t catch and run?  
Or nothing happens?

Mustingman’s question must be answered to get onto the right path toward a correct diagnosis.

I think the Muse 3 day old question was posted on the Car Complaints site as a comment and not a real question . I doubt if Muse will ever post again.
