Kind of sounds like a vacuum leak, too much (false/un-metered) air being allowed into the engine.
During start up and during warm up this “leak” could be causing the engine to run to lean and stall out. After the engine warms it doesn’t need as much fuel and the possible vacuum leak is causing the high RPM due to the false air getting into the engine.
