Car runs great for awhile @ idle, then rpm's begin to fluctuate ending in a stall. No trouble codes will set. While driving it feels like there is a flat spot in the TPS, but this is not the problem as I have just replaced it. Car will restart immediately with no problem, then goes through the same routine after a few minutes.

This sounds like a possible fuel pressure issue. So I would suggest starting with checking the pressure to find out if it stays steady when this starts happening or it drops.

Here is a guide that will help with this:

If this checks out then here is another guide that will help with possible causes of this issue:

Also when this starts to act up, unplug the MAP sensor and find out if this clears up or doesn't stall. If so then you have a MAP sensor issue.

I am attaching the info on this below. Please run through this and let us know if you have other questions. Thanks
