Perhaps you were just unlucky. The engine dispatch reliability and inflight shutdown rate of the P&W engines on UA's B777s are very similar to those on other earlier twin-engine planes. The former rate is well into the high 99% range, and the latter is comfortably below the ETOPS-required rate of 0.02 per 1,000 engine flight hours. I don't mean to say the engines are problem free (because they are not), but I don't believe there are any serious abnormalities.
