vacuum failure was in a twin (as was one of the electricals), and was

continue. Then the right engine quit for unrelated reasons. That put
me in a single-engine, partial panel situation. Also, tops were above
my single engine service ceiling. And there was icing in the clouds.
And there I was, single engine, partial panel, shooting an ILS while
ice was building.


Sounds to me like you need to be spending a bit more on aircraft
maintenance.
