Itsmikem,
Here is a file, that is set up in the way I understand you have it.

Tell me what is different.

It is difficult to know what you have in your file. Guessing is not my favorite thing to do, as it often wastes more time than it does good.
However, perhaps select everything in the Object manager and paste this in a fresh new scene. Then set up your render-settings freshly, and check if there is a difference. If this works, go back to your problem scene and save the render-settings, open those in the newer scene, and see if the problem appears again.
Go to the frame where it doesn’t render and create a new camera, select that camera, so you know if it is at all a relationship to the Morph camera.
All the best
