Heating or fan issue?

On my last couple of prints, the part cooling fan suddenly kicks in at 100% and at the same time the hotend temperature drops resulting in a shut down for Mr. Klippy due to a heating error.. Any thoughts?

check the cooling tab in your slicer, things like overhangs or bridges can have a 100% fan speed setting

This might actually be the sinner.. If I recall correctly, it happened right around the smaller parts of the models, and the layer time might well have been under 10 seconds. Thanks for the tips, I'll tweak this setting 👍🏼
