The abs light, advanced trac control indicator light, and dash lights are flashing on and off intermittently for several seconds. Alarms beep and the engine loses power. This has occured multiple times over the past several weeks. Then coming onto the freeway this morning it occured again and the engine shut off. It would not restart. After almost getting hit by another vehicle as a result of the engine shutting off, I was able to pull over and turned off the key. Tried to start the van several times and after a few tries it started and I was able to get off highway without getting hit. This is a reoccuring problem many 03 Windstar van owners are experiencing. Called Ford and they said it is not a documented problem with them. I have read hundreds of comments from other owners experiencing these same problems. Ford dealerships have repaired/replaced various components to correct this problem but it keeps reoccuring. Something needs to be done. It is a design thing.
