If the MOSFET is overheating, you can replace it with one that has lower Rds On. The IRLB8743PBF from digikey can even drive a pcb heat bed without heat sink.
View ArticleRe: Heated bed hot mosfet
You need something with a much lower Rds On. Even at 0.02 ohm, which is not much different than what you got, you'll need some pretty beefy heat sinking. Here's one from digikey. The part number is...
