Judging by the trunk size it's pretty elderly. Cherries don't live very long. I'd guess it's just natural decline through old age.

Holes in the leaves: shot hole disease. A common disease with Prunus species. Doesn't look too serious.

Oozing sap: disease called gummosis. This disease can be the result of stress, injury, canker, another underlying disease.

Flowering cherries have a whole host of disease issues.......one of the primary reasons they do not live very long. The oozing sap is gummosis, a common occurrence with a wide range of causes. Holes in the leaves could be an indication of shothole, a common Prunus issue with both fungal and bacterial origins. Could also just be a minor insect problem.

It may be time to consider replacement.

If you had borers, I'd expect to see both sawdust and frass. I don't see either.

thanks for the input although it makes me sad the tree has been a focal point in my yard especially in spring anything i can do to help it a few more years? or should i plan for a spring replacement

It will struggle on for a few more years, although it will never get better and overcome the decline. So not a huge rush to replace.

FWIW I have many old weeping cherries that have rallied and soldiered on for many more years. Just treat it like an aging relative.
