Fuel pump failed within a minute of initial warning and performance indicating a problem. While driving ~60 mph on the highway, available power dropped to zero within a couple tenths of a mile, *barely* allowing me to move to the shoulder. Screen error/fault indicated vehicle was ok to keep driving but to schedule service soon. Car restarted an ran for another tenth or two of a mile so I was able to move out of the dangerous shoulder off-ramp location to a slightly better shoulder location. Dealership diagnosed a failed fuel pump (10-20 psi of available pressure vs 60+ normally). They replaced it and a control module to address the problem. No parts were retained by me. Until that trip I experienced no signs of a fuel pump or power delivery issue. Vehicle had ~46k miles on it and was operating normally until that point.
