The foal may have had failure of passive transfer, which is when the foal doesn't get enough colostrum from the mare's milk right away, and therefore doesn't have enough antibodies to ward off infections. If the foal doesn't nurse within the first 2-4 hours of life, it will not do well without getting intravenous replacement plasma and other supportive care.
