My engine cuts off when I drive in a hot temperature weather e.G (desert areas ) but runs smoothly in the coastal area. In my opinion is suggested that it could be a fuel pump and I replaced it but still I did not get this right. What could be the problem?

Hot engine failure can be caused by many things. My first item to check would be the ignition module and then the crankshaft position sensor. Both of those can cause engine shutdown when they get hot, but may work fine if they stay cooler. The problem with both is that testing them for a heat failure issue isn't easy and they will not show an issue until they fail!
