Why not sustain a survivable internal temperature with chemical
exothermic reactions. The internal environment could be heavily
insulated and some body of fluid surround (either directly or in some
sort of bag) the electronics. The walls could be lined with sealed
tubes of a reacting fluid compound. At determined intervals (measured
temp vs time etc) a fuse could be burned that cut the end of the bag,
one wall of the bag could be Kynar (Piezo Co-Polymer)plastic that
will bend when energized (very low power) this will eject the fluid
into the main body of reacting fluid, a chemical process will take
place and the internal temp is monitored until another "dose" is
needed.
I have no idea what would be suitable chemicals but I am sure there
are plenty.
The other unopened bags could even act as a stirring source since
their respective piezo linings could act together in a synergesis of
stirring.
I have experimented with Kynar... it will do this.

A PIC controlling it of course.

Maybe I have gone mad?
Ohh look that mans gone mad!
