Fuel exhaustion certainly accounts for a lot, but there's also
misfueling, fuel contamination, and intake clogging by widespread
particulates.

What's "misfueling"? Sounds like fuel exhaustion to me. As for the others,
you're right to the extent that all engines are run from the same fuel
supply. Many twins have separate tanks for each engine and may or may not
suffer the same problems.

In any case, the incidence of those failures is extremely low, compared to
the total number of failures (not counting fuel exhaustion of course which,
if I recall correctly, is the number one cause of engine failures).

The fact remains, having a second engine *does* significantly increase your
chances of an engine failure, just as having extra cylinders increases your
chance of having a cylinder failure. In most cases, it's a worthwhile
tradeoff, but one shouldn't pretend the tradeoff doesn't exist.
