sounds like its a computer problem. sounds like the air fuel ratio is off. maybe when your engine is cold and the computer runs the engine rich ( where the ratio should be) it runs fine but once it warms up and the computer lowers the fuel air ratio is ends up running lean. This is the only thing that makes sense to me. if it were exhause restriction then it would also be affected when it is cold. Check the computer. something seems wierd there. Is there any way you can trick your computer into thinking that your engine is always cold? if so then it should run fine. then you know what your problem is.
