Dying
 

My truck will die like I have ran out of diesel I'll get out and push the primer button thing 4or5 Xs and it will start after a couple of tries. Then a couple miles it will do it again and then sometimes it won't do it at all. Has anyone had this happen. Also while idiling the air conditioner will blow hot but it's cold as long as it's moving? Any suggestions please

probably need to rebuild the filter head and have someone check the refrigerant.
