In the morning (used to)the brake light stays on until I drive for about 10-15 minutes, now sometimes it stays on or comes on when I step on the brake to stop.

Check the brake fluid. As the brake pads wear, fluid is displaced from the reservoir to the disc brake calipers causing the fluid to go slowly lower. The brake fluid reservoir should be filled to the "Full" mark. I just did this on two cars in the last 2 weeks.
