I'm having a problem with my accord It will start and it sounds great it stay's on i can rev the motor but when i put it in gear and try to drive it dies out what could this be ???

 

Try to clean your throttle blade inside the throttle body and IACV. Those may be dirty and causes air restriction to where the RPM is so low that when you put in under load(in gear), it just shuts off. Once you get those cleaned out, adjust your idle speed.
