Default Reduced power and check engine issue has reaurfaced

hello I could use some feedback. Iíve been a shade tree mechanic for five decades but I am a master of none .
I recently acquired a 2003 Isuzu rodeo with cosmetic damage I replaced the front bumper ( bent) hood and put a windshield in it . I be put a couple of hundred miles on it she runs sweet and then the issues began. Iíve owned 6 or more previously they a great around town and easy on my BAck Iíve had lots of back surgery.
Driving to church one Sunday am I made a hard right turn onto a paved side road and she went into limp mode... reduced power light and check engine light etc.
limped her back home and as a shot in the dark I first cleaned the mass air flow sensor with some carb cleaner( we get tons of pollen here in Texas)... and after a few start and shut off and restart... both lights went out and back to normal driving . 3 weeks later sheís. BAck into limp mode ... I clean the mass air flow again without any change. Iíve got a complete identical 03 parts Rodeo so itís a help. Codes read at Oriellys say accelerator position switch , TPS and a variety of others. Iíve changed out accel position switch, TPS, installed a NEW mass air flow sensor.... and by recycling the ecu by unhooking the battery I can get her out of limp mode but when I attempt to drive her she goes back into limp. Iíve tried several things.... have read what I can find online.... I wonder if I have a broken wire in the harness. Signed .... all played out at the Rodeo. Btw itís the v-6
