I have a 1986 D50 sport 4x4 and it runs and drives great except when you hit about 50mph it then starts cutting out and losing power. I first thought fuel filter so I replaced both and still same problem. I am going to test fuel pump today and if that is not it I am going to rebuild Carburetor. If anyone has any suggetions that would be great. I have never worked on one of these before and its a friends truck. She is in a bind and is a great person so I am trying to help her out by fixing her truck.
Thanks
