MAPed Blue Top Swap, NOT staying running! Please Help?!

[Nanaki]

It will start and run( Idle ) fine sounds normal to me no sputtering or anything as far as I can tell. and it will run for a good minute maybe alittle more and then die. However this is running with the Injector Resistor wires tied together and then tapped into the yellow injector wire. I will rewire it as stated above and see if that helps...
But Ivan to answer your question it seems to be idling fine. It will idle at 1500rpm or so.. Not every time but some times it will sorta flux in idle like.. 1500..then drop to around 1400 or 1300 rpm and back up to 1500rpm kinda like a wah wah wah fluxing if that makes any since at all. But I think it started to do that only after I had started it and idled it, killed it and started it again and repeated while tinkering with it.. But in the long run it doesnt seem to bad while idling..

As I said before I will rewire it and post up later on if that helped or not.. Just a thought that crossed my mind.. It wouldnt have anything to do with the TPS would it? just thinking that maybe that is why it kills over if you try to give it gas.. but maybe Im over thinking it abit to much.
