Have you replaced the fuel filter,and or checked the fuel pressure to make sure fuel pump is running correctly?
Yes I took it to a shop and they couldn't find anything wrong with it
If you have no engine light,and fuel pressure has been checked,you may need to have the PCM checked and reflashed,reason why i say this is no engine light with car loosing power there is and issue with PCM.
