I was beginning to suspect the starter before your video. I have 2 brand new batteries, well cleaned and good connections. I even keep a battery tender on them when it is parked. So it was the leading thing I suspected.... now watching your video, that is similar to what mine does... so looks like I need to order a starter..... it will start, but it is like the batteries are dead. I know they aren't as I lost prime not long ago, so I had to crank longer than normal... and the starter was still slow.... but it cranked way longer that it should if the batteries were as low as they sounded. But, once the engine is warm... it seems to do ok until it cools off again. I had a Jetta that would do the same thing, and it was the starter. If I kept it plugged in, it would start, but if I let the block get cold, it needed a jump to start... I need to replaced the plug on the Excursion, so that is my next test to see if it is the starter.....
