Dude I think you need to take it to a shop and get your engine checked out. Your description of the problem is "poor" at best.
So far you have told us that it won't start:
1. You have over heated it
2. Loss of power
3. Bogging
Sounds like I would have the base engine compression tested before I would go any further into this.
However, you are also describing what might be either some MAF sensor problems or some distributor problems.
