Thanks for your response. My mechanic replicated the problem by letting it sit idling for about 2 hours then driving it. Once it started to act up, it did so constantly until they shut it down. A computer check said all eight cylinders were misfiring but did not show cause. It doesn't seem to show up driving short distances. When I drive for over an hour or for about 30 minutes in bumper to bumper traffic, it starts to show up. I dropped it off at the dealership over the weekend but they wont be able to look at it until Tues or Wed. Things are way backed up in New Orleans. When my mechanic put in a new battery, it ran fine for about 2 weeks before the next incident. Apparently draining batteries, engine shutdowns, and weird electrical events are common in suburbans but I have not heard a definitive cause yet. I added nothing to the suburban since it was purchased. The only thing I use is a GPS which I unplug every time I stop the vehicle.

hey everyone (i know this is kinda off topic)
My dad and I just bought a lot of sound equipment for out boat but since this is the off season we wanted to keep it in our suburban. we dont want to replace the factory head to have pre-amp signals since it ties into the dvd and steering wheel controls. we are going to run the signals into the powered signal option on our amp and get the signal from the small stock sub. the problem: we dont know which wire sends the sub signal without pulling out the whole console on the sub. If anyone knows the pinout diagram or know a website i would greatly appreciate the help. its so hard to find the little information you need.

That's because GM used half assed ABS systems in many vehicles during the 90s. Many were a single or two channel setup. Meaning if one wheel started to lock up, all 4 wheels would be effected when trying to get the wheel that's locking to gain traction. I hope by now, they are using a 4 channel system, where each brake can be controlled independently. With the 3 and 4 channel setups, you'll rarely get the ABS activating while breaking into a corner and in the snow they work much better.

Based on your comments it seems like your problem is heavily temperature related, i.e. when the mechanic lets it idle for 2 hours to heat up or when you drive it long enough.
Then you get misfire in all cylinders, which talks about a serious timing problem.
Have your mechanic to change the crank shaft position sensor. It is a $63 + tax part. I changed mine in my Tahoe and it seemed to be of some help for my issues at the time. This sensor is mounted in the side of the engine and will get hot when engine oil heats up since the oil is slung on the sensor by the wheel it reads.
This sensor really changes temperature big time and can start act up when hot.
Sensor is located behind starter motor so it takes a little bit work to get to it as the starter must be removed first. Your mechanic should have no problem to get there though.
After sensor change you might get a check engine light and a code indicating misfire. If this happens you need to have the sensor re-learned by the computer in your truck, which procedure is available only at the dealer service ($75 or so) I believe.
The other sensors that have to do with engine timing are MAP sensor, cam shaft position sensor and knok sensors. MAP sensor should not be temperature sensitive that bad but the cam shaft position sensor probably is just like crank shaft position sensor is. In my truck this sensor is a little bit harder to get to as it is located on top back part of the engine. Knock sensors are located between intake manifold and engine top so to get to these the manifold has to be removed. Your engine probably has them in same locations.
I would start with the crank shaft position sensor for eliminating your problem.
#436 of 1043 2002 Chevy Suburban Suddenly lost all power
Nov 01, 2005 (8:17 am)
The title says it all, does anyone have any suggestions? Can a battery suddenly die with no warning? We were loading up the kids last night to go trick or treating and the lights were on in the vehicle, when I turned the ignition switch, the whole car went dead. I went out there this morning, and the remote for the door locks won't even work!

Battery can short out and die just like that.
Check your battery terminals though. As it happened when you tried to start it it could have burned a cable or otherwise have a bad connection.
#438 of 1043 Whats wrong with my 1987 suburban?
Nov 03, 2005 (1:26 pm)
When you start it up it starts just fine but it dies it won't idle unless you keep on pushing the gas and if you take it out of park it dies we have replaced the
Oxygen sensor, electronic control mogul, plugs, wires, distributor, roder button, map sensor, fuel filter, god knows what else can you help me.
#439 of 1043 Drivers Side view mirrow out of whack
Nov 03, 2005 (6:13 pm)
I am seeing double. I have an auto dimming drivers side view mirror that seems to be out of whack. especially at night. Is there anyway to realign the mirror or should I just replace it. And how do I do either?

I had the same problem. Check for loose battery connections. The suburban goes in a shutdown mode, and should start again in about 30 minutes.

Same thing happened to me with my 2002 (65,000 miles). Only thing that has ever gone wrong with the truck. Put a new battery in and everything was fine. Good luck.
