Randomly stalls at idle. Sometimes continuously. Always starts up. Not fuel tank

You might try checking the idle air control valve. Over time, road grime, dirt, and generally any foreign materials can prevent it from operating properly. This prevents enough air entering the combustion chamber at low engine speeds. This will not always bring a code up with obd. You may try putting a small bit of vaccum tubing on the stop for the throttle return (preventing it from closing fully and suffocating the engine). If this works, remove the vaccum tubing and replace the idle air control valve. You may also be able to clean it using an all purpose cleaner that's sensor safe, however it is not recommended unless you are in a pinch.
