Not very likely. The molten interior of the earth has always had only one thermal destiny ... gradual cooling until it finally burns all of its fuel and goes entirely cold.
That doesn’t sound right. The earth’s core has no fuel.
See below ...
The flow of heat from Earth’s interior to the surface is estimated at terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of the Earth.
