Hello,
My guess would be that he's a bit UT at BT which is why it's getting tricky. If he naps 2hrs 1.30-3.30 that's only 5hrs until BT at 8.30 so he's possibly just not tired after such a long nap. Have you considered capping the nap?
That, or could he have 2 yr molars on the move?
How old is he exactly?
What are the NWs like? How you do deal with them?
What time is his WU in the morning usually?
Sorry for all the qns, just trying to get the whole picture
