Hey how are you,I will try to help you with this issue

the engine module or cem module or abs is detecting a fault and it is sever enough to tell the computer to put vehicle in what we call Limp Mode or Reduced power ,where it want let you go pass 10 or 20 to keep you from damaging engine ,

a misfire , like plugs and coils will cause it , a fault in the abs or body modules will cause

this here issue ,you will need a factory scanner or equivalent to run a diagnostic scan & retrieve fault codes from the Vehicle modules and based on these fault codes we can pull up a Pin Point troubleshoot and be accurate on it ,If you do get it scanned ,you can post the fault code back here for me and I can help you further on it and be more accurate .

when you turn switch off to on , the car computer will scan for fault ,if it sees the fault it set limp mode right away and sometimes you can drive a little or until engine gets to operating temp then it will see it .

so you first step showed be having it scanted ,do we have fuel or spark or other issues causing to be accurate and not throwing parts at it
