I've been in that very same position flying a SW3.
Over a period of time of about 6 months I found myself (PIC) in an engine-out situation, 7 more engine-related failures with no engine stop, Nº2 ITT unserviceable (would only work during start-up), Nº2 Torque lying everytime (and not a linear lie at that, fine in cruising, 500 lb.ft off during approach...only the turn coordinator would indicate a proper symmetrical thrust). ETC ETC
I resigned. I'm 28 and every cell of mine is keen on flying everyday. This is not flying and an insult to our profession. In fact, I accepted an offer to be ARO-AIS operator at my local airport, plus a non-flying position for an heli off-shore operation.
This means that I will not fly for an entire year, save for the odd CFI gig at my flying club. I'm happy.
