It's really difficult to positively diagnose a plant problem without being able to see it but what you describe are classic symptoms of a disease called Fusarium wilt. This is a common tomato fungus that lives in the plant's vascular system, which carries water from the roots to the leaves. There is no fungicide that is effective against fusarium wilt so there's nothing you can do to cure the problem. Allow the plants to continue growing and ripening the fruits. When the plants collapse, harvest the fruit and remove the plants from the garden. Next year plant your tomatoes in a different part of the garden and when you do select transplants or seeds for planting next year, look for the most disease resistant cultivars you can find. Most tomato seeds or transplants are labeled with a code such as "VFN," "VFNA," "VFNT," etc. This indicates that the plants are resistant to Verticillium wilt (V), Fusarium wilt (F), southern root-knot nematode (N), early blight (A), or tobacco (tomato) mosaic virus (T). Best wishes with your tomato plants!
