Hey man. First thing I would check is the blower motor itself. Sounds like the motor is maybe getting hot & weakens after time? Just guessing man. Good luck.

The evaporator is probably freezing up.

Just took mine on a 6 hrs trip and noticed this. Its happens rarely. I've already replaced blower motor, blower motor switch in hvac panel and cleared out airbox of leaves. It all made things better but it still does it. I know its not the blower motor resister cause its bypassed on hi fan setting.

with 8 lug on this....dunno what else it could be
