Yeah, something similar happened on my Moho probe mission, the solar panels were the single, non-tracking variety, so as I was going to burn the Moho Inclination Change burn, I wasn't facing the sun, and the probe had no power. As I recall, though, it wasn't a total loss, it did a fly-by of Eve, and it was my first (and as of right now, only) Dres flyby mission. The Flying Lemur, the best piece of low-tech junk I could ever have.
