Sudden leaf drop is likely an infestation or disease issue.
I’ve included a link that may help you determine the exact issue.

If you determine the cause, use the treatment as listed.
If you are unable to determine a cause, treat the plant with Neem Oil. Neem Oil works as both an insecticide and fungicide.
Remove and dispose of the dead leaves around the plant.
Here is a link with more information.

I do want to mention that it is possible that plants can be affected by accidental herbicide overspray. If neighbors or even lawn companies have recently sprayed, this could be a possibility. In this case other plants would show the same symptoms.
