2000 Pass Intermittent Stutter

[jggaffney]

I have a 2000 Passport with 120k miles. In the last 2 years, I have replaced the shift indicator switch and the intermittent wiper relay board.

Lately, the truck has had an infrequent stutter. I'll be driving normally, minding my own business, when the engine will lose power for a second. The "Check Trans" and "Cruise Control" indicator lights will come on. After about a second, the power will resume and things will be normal. If I was driving with the cruise control on, it will shut off, but will restart normally. Sometimes, it happens when I go over a bump, but sometimes it just happens.

My mechanic did a transmission check, including downloading any trouble codes from the computer, and didn't find anything. He and I agree that it sounds like a poor electrical connection somewhere. However, with the miles of wiring in the truck, I don't want to pay him $90/hr to look for it. Does anyone have any suggestions that will narrow down the areas where we should look?

Thanks for your help.
