Fuel pump or fuel pump relay. 569sel
 

Anyone ever have this happen? all of a sudden today my car lost power. Would not go above 30mph. Died many time from idle.
After 20 miles of this it went back to normal for the last 30 miles of the trip.

My first thought is one of the fuel pumps took a hike. My next thought is the fuel relay is acting up, but I donot know if that can cause loss off rpms.

Any ideas
Thanks
