2017 Lexus IS FUEL/PROPULSION SYSTEM

I was driving my vehicle and then the entire car shut off going about 50 MPH causing the car to immediately stall. Nothing eventually worked making me have to push my car onto the side of the highway. Replaced the alternator and battery. Eventually got my car scanned and the issue I’m having is a fueling system problem. Did some research and my car 2017 IS350 f sport did eventually have that recall issue. The vehicle was not showing any problems before hand it just happened.

I have been having problems with hard starts, rough idle, engine dying. My vehicle is experiencing all the same reported issues as a recall issued for a fuel pump on my make/model. My VIN however, is not covered under the recall. I've contacted Lexus and they said that if enough people complained that they could make this fall under the recall. It only has problems at idle and upon acceleration. Once a decent speed is reached, I have no problems. This is intermittent. I've also taken it to a Toyota dealership where they kept it for 2-3 days and could not figure out what the problem was, although they witnessed all the issues. I'm marking September as the date of the incident, but this has been ongoing since last year and currently giving issues.
