Your Ignition module that you had checked is probably bad but it does not break down untill it get hot. I had a similar problem with a oldsmobile ignition module. It checked good also but the car would not run with it in. When I replaced it the car ran fine. Make sure you put the silicone goo under the module because it helps to tranfer the heat

My 99 bonneville has a stalling problem. I will be driving down the road and it just cuts out. The weather conditions dont matter. It doesn't matter the amount of fuel. The common denominator when it does this is no power to the seats and windows. everything else works. It might take 5 min up to a couple hours to restart. I pulled all relays under hood by fuses and it still staarts I ran a ground from engine to fender and still didn't help Anyone have any suggestions.

I'd have to look at a factory service manual and figure out some circuits, but I'd sure be checking the battery for a defective internal contact at the time it happens. A few broken posts have made and broken contact while driving for people.
 
Then I'd check the positive battery cables, cutting into the plastic near the ends looking at the integrity of the copper. Some people have reported deterioration due to acid from the battery terminal seeping and running down the cables.
 
AND pull the parts of the positive cables apart. Inspect the lead piece between them. Clean them up.
 
Does the car crank but now start or is there no crank? Power to the starter?
 
I'd have to look at power to the seats and windows. I would think those go to the relay panel on the firewall. Check the positive line feeding there for good connection.
 
Depending on those symptoms about whether the car will crank and not start or won't even crank.... try to use logic from there.
 
A good set of Helm factory service manuals from Ebay for 1999 probably a 3 volume set would help you a lot right now. If you shop, just be sure to get all the volumes and don't buy a substitute.
 
you also might use alldata at your local library to search out the wiring diagrams.
 
I do know also that some people have had trouble with the ground busses under the door sill plastic right where it meets the A pillar. They corrode due to moisture. They are wrapped in tape and bundled with the wires going along the sill to the rear. There is one on the passenger side also.
 
The power seats and window dropping out made me think of that. On my 93 the AC would default to basic with defrost and AC compressor engaged and the pwoer door locks would not work. I figured out it was the buss on the driver side. It rarely happened and I never got to fix it before we traded the car.
 
I do not know if there is any ground there for a car that's running that would cause it to turn off. A check would be to hit that area with your foot to vibrate the wires and cause the corrosion to make contact again.--worth a try.
 
But I'm betting on cable trouble at the battery. A few Bonneville people have put on new cables to replace some bad positive cables.

bigboy11, What if you smell unburned gas in between the fuel filter and the tank? Also what or where would I find the A curcit , it says on mine A curcit Mass or Volume Air Flow Inificent?????? 1500$ later, not buying MAF either!!! I clean it and it will run better but after it sit's and then started it runs rough or will stall with a harder shift as it goes along...

I'm curious if you ever solved your problem. My car is doing the exact same thing, but regardless of the temperatur oustide. Mine is a little newer, too (2000). I've had some say it is either the crankshaft or camshaft sensor or the ignition module.

#195 of 233 2001 Bonneville dies while driving by carp210

Nov 22, 2010 (9:34 am)

Having this problem for a year. No codes, mechanic says he does not want to just start changing parts, hit or miss. Car dies at highway speeds but will start back up and run fine for months. Wife afraid she will get rear ended. Also the car stutters then tach drops to zero and stays there but car continues to run fine. When engine is re started tach works fine. Read some where to try the power windows when engine dies to see if they work but not had a chance to try that. Not sure if this is related but twice the car would not start in park but started fine in neutral. How can I narrow it down without just replacing parts. Car only has about 46,00 miles.

Finally we have it fixed. Died twice with in 10 minutes but started right up. Took it to my local mechanic and he drove it it for a few days (40 miles) and it finally died on him. When it re started he noticed a slight miss which told him the timing was not right. Turned out to be the crankshaft sensor. Everything is working fine now and I did not have to waste my money on a hit or miss approach. Nice Christmas present.
