Unhappy Rpm drop

I have a 03 Trailblazer and Im having some issues with it. Anytime I coast or I let it idle it dies. It always starts back up. I also noticed if I just barely hit the gas petal it will start to die then rev its self really high. I have changed the speed sensor, Fuel Filter, Cam Sensor, and Camshaft Actuator. I also have cleaned the throttle body. Not sure what else it could be. Please help
