well just want to know what yall think

I can drive my car for about 15-20 mins then it just starts to break up Real bad. At first its when i transition into boost then it will start to do it when i am just in vacume. It will start to sputter and back fire, and the whole car will start to shake and basically go no were. WTF can this be? I got new spark plugs and i borrowed some coil packs and its still doing the same thing. Also when i turn the car off and then back on real quick the car bearly idels, like it will just sit at 200 rpms untill I turn it off and let it cool down then it will drive fine but then do the same thing all over again.

Any ideas as to whats going on?

thanks
