As I was driving at 55mph on the hwy I started smelling gas. I thought it was the car in front of me so I was just going to pass him, but quickly realized I did not have the power to pass another car. So I pulled over on the highway and got out of my truck and noticed flames dripping from the center of the vehicle by looking at the front driver wheel area. I tried to put out with a fire extinguisher that a bystander had given me, but it was just too late in the truck was engulfed in flames.
While operating the vehicle inside of a car wash, with the transmission in Neutral and the engine at idle (car was propelling the vehicle) the dash chimed, showed an error message for STOP START REQUIRES RESET, shifted into park and set the parking brake uncommanded.

The only remedy to get moving again was to STOP the engine, manually shit to PARK, restart, then release the parking brake.
