Check Engine Light On problems of the 2017 Ford Expedition

While getting on interstate my 2017 Expedition el 4x4 was shifting and coming up to highway speed , when it seemed to run rough and felt like it missed a shift. I let off gas pedal, engine roughness temporarily went away. Now I'm getting closer to getting on highway , applied gas again and engine got rough running again and tool symbol appeared on dash . I lost all acceleration and power to wheels while trying to enter an interstate. Very dangerous and life threatening if I did not have a long shoulder to pull off on. Pulled over stopped engine. Let sit for 5 or so mins. Started up and tool symbol was gone. Got on highway up to speed this time then same thing happened again. Rough running , lost all power to wheels, tool symbol appeared again but got the check engine light this time. Luckily I was passing an exit and had time to get off interstate 77 before I got run over from behind. Stopped n restarted. Got truck to my mechanic and they pulled a throttle body code on the truck. I had them reset code to see if it happens again because I have an ally extended warranty which we'll see how using that goes. I am driving truck with less issues trying to get code to appear again to take to dealer for a fix. Have gotten the tool light to come on 2x but no check engine yet.
