Need Help please! Throttle cuts out to 2500rpm no codes.

Not too sure this is the best spot to post this, but it seems more busier than the lancer specific page so hoping i can get more insight for this issue, Aloha everyone, i got this car about two years ago, its a 2015 Lancer GT manual, only has a cat back exhaust and no other mods. this seems to be a really weird scenario where the car idles and runs perfectly fine, no weird revs or rpm bouncing either cold or hot both are good. Now the issue seems to occur sporadically while driving, as long as the engine is under load it will randomly cut my throttle and drop the rpms down to 2500rpm steady. i can release the pedal and press again to gain control for 3 seconds then it cuts off again. i can raise the rpms to keep up with traffic by bouncing the throttle but holding it more than 3 seconds will cut off. if i do a key cycle it will go away but return at a random time during the drive. I can depress the clutch the car will rev up perfectly fine or in neutral but once in gear and under load, the issue will arise again. There's no codes besides my airbag light from my removable steering wheel but that shouldn't be causing these problems. If anyone can help or possibly has experience with this or has seen or heard of this issue please help me, this has been going on for about 2 weeks now, i changed out my oil, transmission fluid, checked my wheel speed sensors, maf seems clean and debree free. my next thing to check would be my fuel system, or exhaust to see if the cat is clogged then lastly my throttle body area. but any of these issues would cause for a light to come on right? I'm just stuck but don't want to give up on this car.
