I revive the plant , it is in a big pot and it about 9 feet tall. There is a little green color on the tops of both trunks. Wanted to know leave it and see if it puts out, or cut it back and replant? Thought we had it in a green house that would keep it alive but not so sure, since all the limbs have fallen off. Had this about 15 years don't won't to loss it. Thanks for your help.
It is best not to do any pruning till all the cold weather has passed. You can cover it during any more cold spells. These articles should help:

The pine was doing very well. Growing tall and healthy until the freeze.
You can remove broken or dead limbs at the trunk.
