Livebearing fishes, particularly mollies, swordtails, guppies, and platys are prone to internal parasites, and specific diseases that target this group of fish. Have you noticed any changes in color of the fish before they die or when they first start acting sick? What is your water temp? What other fish are in the tank.
Also, what is your ratio of male to female guppies? If there are not enough females in the tank, males will chase females to the point where they die from exhaustion, because of their natural breeding habits. It's important to either keep all of one sex or to have 2 females for EACH male in the tank.
Does this help?
If you can provide more info about the guppies, I will do what I can to help.
