Narrative:

Emergency landing due to fuel starvation. Fuel planning indicates we should have had 1 hour 15 min fuel remaining at time of loss of power. Full tanks at departure point, time of departure XA15 local. Fuel starvation at XD30 local. Calculated fuel burn over previous 15 hours indicated 8.5 gph burning full tanks (39 gallons usable) over 3.25 hours gives 12 gph consumption rate. Suspect fuel leak or loose gas caps. Landing uneventful, no injuries, no damage. Inadvertently squawked 7500 instead of 7700.
