Your car will turn on and struggle at 100-200 RPM then die/stall out
If its a turbo car it will stall if the blow off valve is not shutting properly as the pressure drop is too much for the engine to keep turning, same with lpg when you idle the pressure in the engine drops and it will stall you can correct this by changing the timing
its probably just your idle kicking in when u stop, this keeps your car ideling at a certain RPM so your car dont stall, and die.
Your Idle Air Control valve may be sticking. Or the engine oil is to cold, thickens there is more power needed to crank the engine.
You can tell if you have a stall converter by observing the engine's RPM behavior during acceleration. If the engine RPM increases significantly before the vehicle begins to move, it indicates a higher stall speed typical of a stall converter. Additionally, if the car feels like it takes longer to engage or move from a stop, that could suggest the presence of a stall converter. Lastly, checking the specifications or design of your transmission can confirm whether it includes a stall converter.

Your 2002 Lexus GS300 may stall when the RPM drops to 0 due to several potential issues, such as a faulty idle air control valve, a vacuum leak, or problems with the fuel delivery system. Additionally, issues with the ignition system, like worn spark plugs or a failing ignition coil, can also cause stalling. It's advisable to have the vehicle diagnosed by a mechanic to pinpoint the exact cause and ensure proper repairs are made.
