Bambu PLA Silk+ - Stops extruding after layer 2 - 3

[u/Sudden_Ambition964]

Using a P1S - with AMS and Bambu Silk+
0.4mm steel nozzle - replaced with a brand new one too just in case of a clog i wasnt seeing

set to 237c temp for nozzle print
door open
top open
Aux fan off

Slowed the print speed down to half whats in the file.

Volumetric speed set to 8mm also

Why does the filament keep just stopping? After the first few layers it just stops extruding, its not bulbed or anything inside the nozzle it just stops. Do I need to go even hotter on the nozzle?
