Brett,
If it was working before the failure, one should always assume a single
failure. Multiple failures are quite rare and are normally induced by
some outside force (incorrect power, lightning surge, etc.)
There are instances where one failed component will take out another
one, but that is rare too if the designer did his job right.
In any case, it is all a matter of probability, but no matter how low
the probability of a failure is, remember that is calculated on a large
sample size. If you have only a single unit, the probability of failure
for that one unit is either zero percent or it is 100 percent - there is
just no other way to calculate for a sample size of 1.

Totally agree. I was somewhat appreciative that FD helped me find the
problem as soon as possible and was wondering if solid type TX would be
a good way to do an accelerated test. From what I'm hearing now and I
agree a FD simulation w/ full QSK running is probably more real world.
You are correct in that all I really want to do is find any underlying
problems quickly so that I can be assured that I'm out of the 0.1%.
