If you inspect the fruit, notice whether there is a spot or small crack near the fruit's stylar end, or its "belly-button." Your tangelos may be suffering from alternaria rot, which is not always detectable until the fruit is opened. This article has tips on how to treat for this fungus.
If that doesn't seem to be the problem, contact your local University Cooperative Extension group. I'm sure they will know.
