LT8640S not restarting in LTspice sim

I am trying to simulate the LT8640S briefly losing power on its input and then recovering. I'm using a voltage divider to supply the EN/UV pin.

The LT8640S turns on with the initial application of power (24V), but when the input power goes to 0V and then back to 24V, the LT8640S does not turn back on. Is there some parameter that I'm missing?

Added circuit image.
