Cocos2d Collision Detection Debug

I have a cocos2d v2 XCode application that I have created and I need an expert in cocos2d/Objective-C to help me out. I have a very simple circular collision detection for my game. My problem is that my player will randomly die without being anywhere near an enemy, not even remotely close.. The thing that confuses me is that it happens at random locations and random times so I know I messed something up. I need someone to help me out and fix this issue. I am a programmer so I have knowledge of this so I just need someone to help me out since I've been scratching my head over this for days now.. My budget for this is very very minimal because it should be such a simple fix. The perk to this project will be that I will keep you as my programmer for any future help I need. So think of this little job as an entry test for future work! I will be taking the person with the lowest bid and the best knowledge of cocos2d.
