I hope there is someone who can assist me with my issue. 2006 LX470, 180K . I have owned it for close to 2 years- It was involved in a minor front end collision before I bought it. No airbags. The LX retains all original factory sheet metal. What was replaced was the Bumper and 1 headlight assembly. Installed a TJM bumper and removed the running boards. I had ALL the fluids changed, belts hoses, etc....water pump.....etc. Ran great until about 6 months ago, it died while driving several times. No Codes. We replaced the fuel pump with a factory part and it ran great for 5 months. Then it started dying again-- on the freeway, it cuts off and restarts itself. And then at low speed, it will die- and will restart on the second attempt. No Codes. So we changed the Fuel Pump relay. Great for a week and then it died again this AM. HELP
