2018 Nissan Titan engine problems

While driving on Interstate 20 at a 75 mph speed in traffic, the truck began a loud knocking noise and the engine shut down. After fighting the dead truck off the roadway from the highway speeds and avoiding traffic, I was able to get the truck safely stopped. Upon attempting to restart the engine, the starter caught on fire. I was able to get the fire extinguished with minimal damage. The truck was towed by a wrecker to my home. I replaced the starter and inspected the wiring harness for fire damages.

1. The vehicle had to be braked hard on the highway to avoid a car that failed to yield while merging. The other vehicle then braked hard and I attempted to accelerate to get in front but the vehicle would not respond to the gas pedal. The engine did not shut off, but the truck would not rev the rpm's or have any response to the gas pedal for about 3 seconds. Luckily a collision did not occur. 2.
