I just can't win...

So I replaced the wiring harness to my MAF sensor and now I have full power when I hit the gas , but now I have a new problem. I think it's unrelated, but I could be wrong. It idles close to 3k rpm and the rpms rev to 3k anytime I push the clutch in. That isn't the real problem though, I figure thats an adjustment that can be made on the tps?

But anyways, sometimes after driving it will just die out of nowhere. I try to start it back up, but it won't until a good while later. I've done a search and some people say dizzy, I just recently bought the car and it was mostly stock except for exhaust and MSD dizzy/ignition. Could the previous owner been trying to fix this problem? Not sure what the problem is, no CEL.....

Yeah the starter sounds strong and I'm not too sure how old the msd stuff is doesn't look too new though. Also I replaced the IAC already.
