Engine would stumble at low rpms then stop. Diagnosed with failing high pressure fuel pump by Hyundai technicians. Replaced part. Problem persists but much less frequently. Restarts immediatly after quitting and performs admirably until the next episode

I have seen the fuel pressure senso go out on these cars and cause this problem, lets do a scan to see if any codes can help us confirm the issue. This video will help
