Couple of things that I can think of.
1. Air flow restriction. Check the cooler if there is anything covering it. Blow air through the fins backwards. If anything is stuck in the fins. This should help in removing it.
2. Thermostatic plate failing. Never heard of one failing to open, but there is always a first time. Would have to change to a new plate to find out. But it works ok on the street. So I don't think it would be this.
3. Your track sessions have gotten longer, and you never noticed.
4. You now have reached the point where you need to up-grade.

1st Lap 160 ->180 (warm up)
2nd Lap 180 ->220
3rd Lap 220 -> 240
4th Lap 240 -> 250
5th Lap 250 ~255ish before the lap finishes and stays at the same point the rest of the session.
Lap 2.25 Miles 1m37s~ average pace Sessions are from 20-25min

It might be the 2015+ nismo bumper lets less air through then the earlier version I had. I have to look at some of my earlier videos this year in detail and see what was going on then.
