2016 SX motor #2 450 miles with IDS Tips ECU

Given my experiences maybe I'm just paranoid. Something I've noticed with both motors is that they die intermittently when warmed up. Like if I've been riding around town for an hour, and I come to a stop, sometimes it just dies. With motor number one it did this three or four times the day before the rod failure. Is this "normal" ? With engine #1 I just assumed this how it ran, until it blew up.

Also I notice that that at just off idle 2500 RPMs sometimes it's like the motor will "catch" I pull the clutch in and give it a bit of throttle and it comes back.. Anyone else experienced this? It might be just me, I'm looking for problems. :-/
