If the throttle switch is always sensing that the throttle is at rest, it will fully retract, trying to control the increasing speed as you accelerate. With this switch showing that the throttle is at rest, any increase in engine speed is seen as an increasing idle, that the system thinks it should be in control of. The isc fully retracts trying to lower this speed. You release the throttle, at in closes to it's hard stop, shotting off airflow past the throttle plates, and stalling. When it stalls, check and see if there is a gap between the throttle cam, and the ISC pintle.
