How do I cross the lava pit?

Hint 1 of 4:

Sometimes when you step on a stone, one nearby happens to disintegrate.

Hint 2 of 4:

There is a pattern.  Watch where you were, where you are, and where the
hole is formed (if there is one).

Hint 3 of 4:

The three stones are in line.  So the stone in your current direction will
always be missing.
