A severe temperature change or lack of water will cause spathiphyllum bud maturity problems.  Make sure your peace lily is moist but not soggy and the air flow around the plant is remaining constant.  I suggest you check for thrips.  I'm not sure of thrips effect peace lilies the same as they do roses, but thrips keep rose blooms from opening.  Thrips are a small slender insect.
