An aircraft has a couple of technical issues 10 days apart and it excites you? You may find it's far more common than you think. It happens. It's not all that unusual for airlines to experience a host of tech issues on one particular aircraft whilst the remainder of the fleet plod on without problems for years. All go through the same maintenance procedures. Just one of those things.
On an Etops aircraft an engine failure is rare. To have two failures on the same engine within 10 days is quite extraordinary. It indeed beggars the question what had been done after the first one.
