Thank you for all of your thoughtful responses! I am a bit alarmed, but also informed, and will check my codes at Autozone tomorrow, I will report back as to what those are. I may also clean the throttle body as a precautionary measure. I am somewhat confused about one thing - if a cooling issue or major engine malfunction were to blame, wouldn't I experience the issue during normal driving? To date, I have never experienced this issue when cruise control is not engaged - even in windy areas as I mentioned. It seems that only the cruise control triggers the issue. As for the question about the coolant temp, the temp reads slightly below the mid mark consistently. I have never experienced a higher temp reading, even during the summer. The car has 102,000 miles, by the way. Thanks again for all of the assistance so far! I will post back with the codes tomorrow. Shaun UPDATE: I had the codes checked with a reader today at Schucks. No codes were present or stored.... Any ideas?

I own a 1998 Lexus LS400 and have experienced an unusual issue with the car. When in cruise control, especially in a windy area, the VSC indicator will come on, along with the check engine light, and I will then lose the ability to accelerate. At that point, I must pull over. I have found that disconnecting the battery for a time and then reconnecting will reset the VSC, and the car will then drive normally. This nearly always occurs when in Cruise Control, but never during normal driving. Needless to say, I no longer use cruise control. Has anyone else experienced this issue? If so, do you have any diagnostic tips or suggestions to lead me in the right direction in terms of troubleshooting? Thank you in advance!
