My suggestion was when low fuel is detected, DISCONNECT THE POWER FEED, and THEN shut the engine down. Two phases.

so the already small fuel tank is now smaller, to solve a non existant problem, reduce run time, cause confusion, extra expense, and frustration from users.

Now a low fuel light would be nice. And it's very easy to implement. Like on my motorcycles (and some cars as well). fuel tank has a thermistor in the fuel tank near the bottom. current source runs constant current through the thermistor, gas keeps the thermistor cool. when fuel level gets low, (below the thermistor) thermistor temp rises as it warms up, signals low fuel light to come on. simple, reliable, and doesn't need any float. very consistent on what level triggers it.

Except the OP was asking about a dual-fuel generator which are typically purchased specifically to run on external propane tanks.

Reality is shutting down by running out of fuel and some sort of sensor that shuts the generator down when fuel gets low effects pretty much the same thing...the generator shuts down with what ever electrical devices still running until power is cut.

If you are manually shutting the generator down (not running out of fuel), it's nice to shut down the major electrical draws but that's a "nice to do". It's not a "your rv electrical system will die" kind of thing.
