2013 Mazda CX-5 electrical system problems

Tl* the contact owns a 2013 mazda cx-5. The contact stated that while driving approximately 5 MPH, the vehicle suddenly stalled and smoke began to fill the interior cabin of the vehicle. The contact noticed flames coming from the electrical fuse panel that was under the dashboard. The fire melted the dashboard as the interior became engulfed in flames. The fire department reported to the scene to extinguish the fire and a report was filed.

While driving on the highway, the vehicle very suddenly decelerated (from about 55 to 40), almost as if it slipped back a couple of gears- it was a jarring and immediate loss of power, and I could hear the engine strain as if it was forced into a lower gear. The traction control system and tire pressure monitoring dashboard lights came on, and the check engine light began flashing. I lost ability to accelerate above maybe 1k or 1.5k rpms.
