2017 Ford Expedition fuel system problems

09-10-19 my 2017 ford expedition has shut down multiple times while driving down the road. The dashboard lights go black and all power is lost, engine, power steering etc. I had the vehicle towed to the dealer on 09-08-19. While it was being towed, the engine compartment caught on fire and the tow truck driver had to put out the fire with an extinguisher. Fortunately, I decided to have the vehicle towed as this entire experience is a life safety matter.

Vehicle started running rough going up a highway on ramp, check engine light came on, pulled over and shut off engine. Restarted engine and it continued to run rough. A couple days later the vehicle stalled while accelerating into an intersection and again the check engine light came on. The electronic throttle body etb assembly has been replaced by the dealer. I feel this is a safety issue, and it should be covered under a recall!
