Other Fuel System Pump problems of the 2016 Subaru Forester

My 2016 Subaru Forester has twice experienced a sudden engine stall while cruising at approx. 70 mph when the fuel was low. In both cases the low fuel warning light was not on and the vehicle showed fuel in the tank with fuel range of 70-100 miles. In both cases once the car was stopped it started again and ran normally until and after refueling. This has happened only at high speed which makes the condition especially dangerous in traffic. After the first incident (@ 42,000 mi. ) I took the vehicle to a Subaru dealer who checked the vehicle and found no explanation. Of course the dealer was not able to duplicate the exact circumstance of the power failure. The vehicle is currently under examination from the second incident which occurred yesterday (@ 50,000 mi. ). I do not know if this is a fuel pump problem but I have seen other posts that suggest that may be the cause.
