does it feel like its running out of gas or it just quits? One would point to fuel and the other to ignition. Why do you have to pop the clutch? it wont start back up with the key? Does this have the ignition switch on the column? With out it actually acting up , no scanner will help find it. You have to duplicate the problem. it could be anything from an ignition switch, to a pcm , to a fuel pump. I wouldnt keep throwing parts at it . Unfortunatly it might have to get worse, or at least get to where it does it everytime you take off , next time it does it , when you try to restart it dont let the key return all the way, if thats the reason you have to pop the clutch. if it starts , then there you go.
