You could try Apple Hardware Test / Apple Diagnostics, but there are only two possible outcomes and both lead to the same result: it may identify a specific failure which only Apple can fix, or it will conclude "no trouble found" when trouble clearly exists.
Either way, it requires a trip to a Genius Bar or AASP: Contact Support.
