When I arrived for duty; I put a fuel request in for 3000 LBS. I was informed that the current fuel load was 3900LBS with a 900-1000LBS fuel imbalance. I was informed that since the imbalance was less than the limitation of 1212LBS that I was good to dispatch. I questioned why the aircraft had 3900LBS of fuel on board; and was informed that due to maintenance/engine runs during the previous night; the night maintenance fueled the aircraft incorrectly. I contacted Dispatch; informed [them] that the aircraft was fueled incorrectly; and now had 3900LBS of fuel on board. I explained that I would have to balance the fuel load and that there could be a loading issue/delay...due to the reduced payload capacity because of the higher fuel load. This was all noted and my flight was released for departure.  My first turn...was completed with no additional issues.I refueled for my [next] flight...with 3100LBS of fuel and departed. No issues were detected on the first leg. On the second leg on climb out a 'Low Level Fuel Light' local alert illuminated with fuel light on the Captain`s [side] and Right Engine Electric Fuel Pump turned on. We performed the Fuel Lo LVL following Failures Procedures. We checked the Fuel Quantities and had over 1000LBS of fuel in both tanks (Total Fuel on board over 2000LBS). We completed the procedure for 'If LO LVL light on one side only.' We had no indication of a Fuel Leak. We completed the procedure per 'No Fuel Leak and if FQI (Fuel Quantity Indicators) is equal or greater than 352 LBS;' 'Feeder Jet pump malfunction is suspected.' We monitored Fuel consumption and burn rate was normal in both engines. We contacted Dispatch and informed them of the malfunction; indications; the procedure performed and our ETA. During the descent at around 900LBS of fuel in the right tank (Total Fuel On board over 1800LBS) the right engine flamed out. We contacted Center.... We performed the Engine Flame-Out procedure then the Single Engine Operation Procedure. We received or clearance to land...and executed the landing with no further issues. Maintenance inspected the aircraft and found the right fuel tank showed 900LBS of fuel indicating on the FQI but no fuel in the right wing.
ATR42 Captain reported that on descent for landing; the right engine flamed out with 900 pounds of fuel indicated in the right tank. Tank was subsequently found to be empty.
