@esteban.montes, I have to ask vs assume- do you have the mosfet bolted to a proper heatsink? - with some sort of thermal interface material (thermal paste, heat pad, etc)?
As @rick_1976 pointed out, this FET requires a more voltage to ‘fully turn on’ than one with a lower Vgs threshold, so it’s going to act far more like a resistor (generating a lot of heat) than a fully-on switch.

Assuming you are heatsinking it well, the STP60NF06L looks like a far better option for being driven with 5V…
