There are many possibilities ranging from insect pests, environmental conditions or disease.

It could be 'bacterial canker'. When tomatoes have bacterial canker, their leaves will wilt, turn yellow then brown and die from the bottom up.

It could be a wilt disease, such as fusarium or verticillium, for which there is no chemical treatment. Solarization of the soil is typically recommended. The YouTube video below will help you identify if you have a wilt disease or not.

Over/under-watering will also cause leaves to turn yellow and wilt. Examine the soil. If it is dry, dusty and cracked, then your plants are under-watered. If the soil seems swampy, the plants are most likely over-watered.
