It took the battery with it. Our cars require a lot of power for all the goodies... I still don't agree. There is a better chance of this being a battery cable corroded or loose.

yes i do agree.. i guess i should have said..

in the worse case scenerio if its not something simple, like corroded battery cables or old battery.. than you should look into your alternator.

I disagree. Check the alternator if you like, but I've never seen an alternator on a Bonneville in 3 years fail in this manner. It'* either a battery connection problem or a corrosion problem.

Agreed Willwren...

Also, (and I have had this happen on an H Body), check the bolt in the center of the MaxiFuse Relay Center. That'* where the main power into the car goes, and this bolt can corrode or loosen, causing intermittent outages as described.

Agree with the alt, but disagree with the cables.

I've been through the battery cable thing, and if the car would be shutting down due to that, he'd loose all power to it.....Or the car would barely crank, if at all, simulating a dead battery.

I'm gonna go with a fuel delivery problem with out load.....Like maybe a fuel pump cutting out, or dropping pressure, loosing power, etc. Seeing how sometimes it'* real hard to start after it has stalled, but yet still has all his bells and whistles.

My $.02......Let the criticism begin LOL

When the engine is shutdown & then starting the engine again, the battery is the sole source of energy to provide electrical power for cranking, ignition, fuel pumps and so forth. The battery doesn't take power from the alternator while the engine is going through the initial start sequence. Once the engine fires & picks up speed, the alternator comes up on line (full field at rpm) and is then paralleled with the battery. The alternator is running at a slightly higher voltage than the battery, this is how the alternator puts amp/hrs back into the battery (charging the battery) to bring the state of charge up to nominal value. Electrical, fuel, & ignition all have to be isolated out one by one. The beast will have to rear it'* ugly head eventually.

OK, I re-read the original post (I should know better than to just go by the last few replies).

Check that the bolts holding the throttle body are tight, and that the Fuel Pressure Regulator is good. My car used to stall like you described in your post. While I was replacing the FPR, I found that the throttle body bolts were loose. Fixed 'em both at the same time, and she'* never stalled since.

I took the car to a different shop and they said the fuel pressure regulator was bad. It has not shut off since it has been replaced. Thanks for all the replys this site rocks.
