Dan I am really sorry to hear about your situation, I know how it feels.

I had couple bad experiences on New Years eve, one was in the mid 80s, when I got my new Yamaha FX1 Electone(top of the line), it died after playing the first 45 minutes...
the music store loaned to me a PSR 6100 or 6300, donīt remember witch one, that allow me to finish the job.

The other party was about 6-7 years ago, at the time I was playing the Ketron SD1, and about one hour BEFORE the people got there, the SD1 died, I was lucky to get it back,
I had to make some quick registrations, somehow, those got lost, I made it just in time, it was VERY stressful, but, the job was done, in fact, I was ask to comeback the
following New Years eve and I did.
