The computer is detecting a problem and sending the car into limp home mode, which explains the lack of power when it happens. Turning the ignition off and restarting it resets the computer, so it will drive normally. It's not possible to say what is causing the problem, but it's likely to be a sensor, perhaps the oxygen sensor, or an electrical connection.
There's no real reason to disconnect your battery when recharging it as long as the ignition is off when you do it.
TOYOTA will advise you against doing it, but they do that to protect themselves in the event something goes wrong. That's perfectly understandable. They haven't done the research and testing to develop an LPG system that works on the LandCruiser. You need to discuss your concerns with your LPG installer. My contacts in the industry suggest there's no problem with doing it. One has run a 100 Series on LPG for some years without any trouble.
