2015 Malibu P0089. Runs fine in city or hwy, but getting off hwy it stalls and takes time to sit before it will start again. How should I diagnose which of these issues is causing the fault? Thank you!

Im having the same issue with my 2015 malibu its showing P0089 its the high rail fuel pressure sensor behind the intake under hood. I'm changing mines Saturday.
