Now for some reason it is flatting right where the boot is attached to the inside of the tire. Perhaps the tube is binding against the patch causing a hole to develop due to uneven expansion rate.
I've had this happen twice in 30 years of riding. What happens is the hole is big enough to let the tube push through but not enough to let it pop. As you're rolling, the tube wears where it contacts the road.
As others point out, a substantial tire boot is required to keep the tube contained. A regular tire patch stretches too much. The only permanent solution is a new tire.
