I cant run your simulation because you didn't include your library. I'll guess that the Rds as a function of Vds of your Mos model is much higher than the one I used. Note that the
FDR6580 has a guaranteed RDS(ON) = 13 mΩ @ VGS = 2.5 V.
Whatever you use needs to have a low RDS(on) with a gate voltage of less than 3V.
ps: I looked up the NDF10N60, and it is totally unsuitable for this task. It is a very high voltage Vds =600V, and very high Rds(on) = 650mΩ with a gate voltage of 10V!

Will you be switching the load on/off as fast as possible when the 430 port pin changes from low to high? At what rate? Are you trying for PWM?
