Pull the DTC codes and look for:
DTC P0461 Fuel Level Sensor Performance
DTC P0462 Fuel Level Sensor Circuit Low Voltage
DTC P0463 Fuel Level Sensor Circuit High Voltage

DTC P1431 Fuel Level Sensor 2 Performance
DTC P1432 Fuel Level Sensor 2 Circuit Low Voltage
DTC P1433 Fuel Level Sensor 2 Circuit High Voltage

When does it do this? Random? After you fill the tank?
