Question about 2002 Chevrolet Suburban 2500
My problem started last summer and occured on several occasions, I took my Suburban to our local Chevy dealer and they could not locate the problem. On days that I drive out of town (on the highway driving 65-70 mph) and it is hot outside my Suburban gauges will appear to be fine and within normal limits and then the engine will shutdown. Once I get off to the shoulder of the road and sit for 10-15 minutes it will start again and sometimes I am able to travel another 10-20 miles before this pattern repeats. It seems to me that there is an electronic safety that is shutting things down. I have even tried not running the a/c to see if that helps and it does not seem to make much of a difference.
I also have noticed while driving that my car make a whistling noise that is most noticeable while travelling in town at reduced speeds.
Just wondering if you guys have any ideas or have run across this before. Any help would be greatly appreciated.
I had the exact same problem on my 2002 Suburban. turns out it was the Fuel Pump. the car would run great on cool days & short trips. But when would drive all day. the car would start to get sluggish. then turn its self "off ". I changed the fuel pump and never had that problem again. hope that helps you..

Mine does the same thing as far as shutting down on long trips---usually 1 1/2 - 2 hours. I don't think it's overheating....it's got something to do with antitheft system
