Abnormal craft that kept lighting up, disappearing, and appearing back up in a different location

I was driving in to Dallas on IH45 headed north with my wife and it was a perfect day without a cloud in the sky and the first thing I saw was a light in the sky that I had kinda noted but didn’t think anything of it. Then I looked away and looked up and it was gone so that was my first clue. I told my wife about it. Then I saw it pop up again and pointed it out to her and we were just observing it for a few minutes. We would see it light up then disappear then show up in a different location and move in weird directions and would move in opposite directions. Then I saw it close and got a better view of it but thought it was maybe a plane then it lit up and disappeared again. And then I saw it again and caught a video. In the video, you can see it stall in mid-air, then start to descend, then speed up at a crazy fast speed, then disappear, light up, and disappear again. After we stopped filming, the craft headed towards a plane that was very obviously a plane and it appeared like they almost ran into each other. Shortly after that, it disappeared again and we never saw it again.
