Delgado's right, the fish ran out of oxygen. This is a big fish, and SH literally breath air from the surface (and not only through water absorbtion)...So it took gulps of oxygen until it wan out in the bag, then suffocated. Poor thing.
With SH, always either leave the bag opened, or place an air pump outside of bag with a hose in the bag for air.
Sorry for your loss...
