It sounds like the kernel module auto-unloader is kicking in.  That would
be strange because once the config is loaded and filtering is started NPF
indicates that it should not be unloaded.

Can you check with modstat | grep -i npf ?  Also, what happens if you
manually modload npf, npf_alg_icmp, etc?
