I was driving 40 mph, when warnings appeared on my dash. "Service Stabalizor control", "Traction control turned off", "power is reduced", and the check engine light came on. I lost power as if engine quit, no acceration, but then came back intermittent. If I had been on a highway going 65 mph, in heavy traffic, there may have been an accident. Power steering remained on. I took to an auto service business, and they were unable to find the problem. Code indicated a fuel pressure problem.
