Motor is a 3800 series 2 i changed the wires/plugs put a new iac sensor and a throttle positioning sensor in got my fuel pressure checked which was ok the problem is that the car seems not to have all its power from time to time if i remote start it, it will either cut off or idle rough untill it smooths out and thats on cold starts but when i drive it for say about 30 mins to 45mins non stop it seems to wanna hesitate/stall under a slight load from a stand still from a light or stop sign but the crazy part is it will idle fine like nothings wrong until i put a load on it and even then i have to jump on it so it wont cut off but when i let it sit for about a hour and drive it no hesitation or stall untill something heats back up could this be a ignition control module?? Also my temp gauge moves from under 200 to past 200 then on 200 would that factor into the hesitation/stalling thing? Mabe a cool and temp sensor?? Service engine code onlycame up as a knock sensor

Unplug your MAF and drive without it. It will stumble at first but should smooth out. If it drives better then the MAF is bad.

Ok coolbeans thanks.... Should i wait until it starts to act up or do it right off back

Really wont mater. If you know it runs bad in the morning, then unplug it then and see if there'* any change. Just don't get on the gas hard without the MAF plugged in. Just drive normal.
