I was driving down my road and the fuel reserve at 40 miles popped up. It immediately showed a error code saying fuel supply then drivetrain malfunction right after... my car shut off, went into neutral no power. I was trying to start it but it would bog down and die Out and turn off after 2-3 seconds.. I got out and hit lock and unlock a bunch of times to try and engage the fuel lines and I got in and it worked... but it keeps happening every so often. Any ideas on why this is happening ?? Fuel pump??
