So how bout this,,, reading through I only see things about stalling, however. I have an 03 hyundai XG350, does not matter what speed you are traveling the engine loses power (stalls) with no sputter or anything. Then a short time later it regains power about a sec or two. And on occasion when turning it will stall and needs go be restarted...starts every time no problem, No codes and nothing I do can duplicate this, just happens on it's own when it wants.... Any ideas I'm at a loss
