It has not happened since the weather turned cooler. I drove it back to New Mexico from CT at Thanksgiving, pulling a trailer, and it ran flawlessly. I have to believe it is an electronic component that controls the fuel delivery, but I cannot get it to happen at the repair garage. Nothing is recorded in the computer. It has been wet, cold, warm here in NM, and it has not happened. You just have to pray that it doesn’t happen when you haven’t got 15 minutes to spare.
