Why would it do this Samurai 1.3 like runs out of fuel going up hill what could it be?

If your Samurai 1.3 runs out of fuel while going uphill, it could be due to a few reasons. One possibility is that the fuel pickup in the tank is positioned in a way that it can't access the remaining fuel when the vehicle is tilted, such as on an incline. Additionally, a clogged fuel filter or a malfunctioning fuel pump could restrict fuel flow, particularly under increased demand when climbing. Lastly, it might also indicate a low fuel level, where there's not enough fuel in the tank to reach the engine efficiently during uphill driving.
