Wow, that would be great if it'* the problem. Did you check the one under the back seat, too? If so, how was that one?

Paul, those connections are funny sometimes. My 95 is picky. When it'* being a bitch, it'll provide power to EVERYTHING but the starter. Even though it'* the same feed. I'd take the connector off, clean it up, dielectric grease it, and put it back tight.

Paul...I fought a lean bank code over slight power fluctuations...

If you ask me..anything is possible. And interestingly ..my car would seem to hiccup real quick..the run time clock would reset at the hiccups. Why if the car technically stalled..couldn't it act like yours is?

I'm not really up on the newer model Bonne'* but I had the same problem on my 90 SSE where as it cranked and started fine until one day it wouldn't crank at all. It was hit and miss after that. The problem ended up being a bad connection at the positive side of the battery. I found that hard to believe since I thought the connection was fairly clean. Sure enough....Bam!. Cranks over every time now. Just a thought.

The more I think about it the more I think that is what the problem was. I had it disconnected a few months ago during the injection system install and it may not have been tightened well. I am going to remove it again and use some dielectric grease as Bill suggested, then make real sure it'* tight.....200 ft-lbs should do it.

Hasn't done it in a while now.

Paul...remember...steel bolt...lead threads in battery Go 1,000 ft lbs

No this was not the connection at the battery (that sits under the rear seat in +00) but the under hood fuse panel connection where the starter gets it'* power from. Steel nut...steel stud.
It'* clean and tight now.

I thought I had it licked but my wife was driving yesterday and it stalled going around a corner in idle and couldn't be restarted for 15 minutes.
My wife had to sit there and pray the whole time that it would start.

I am trying a suggestion to replace the original 6 year old GM battery, so tonight I popped in an Optima red 1000 amp battery to see if the problem persists.

......starting to **** me off.

I can relate, I absolutely hate it when the car dies while my wife has it. I sort of feel it'* my responsibility to maintain it. I know I'm no where near the best mechanic around but I try to keep her safe.
I always said that if I can get 5 to 6 years out of a battery, I'm happy. Mind you they've been building stronger batteries but still, I think 6 years out of a battery.........you've done well. Preventive Maintenance I always say.

Ask them about the problem and see if they have any service bulletins on the issue. I used to get these of the internet for free, but now I think there is a charge for them. You never know, might shed some light on the issue. At the same time, I always give them my VIN to make sure I haven't missed any recalls The chevy dealer in town here is not real nice on the phone, but the Pontiac one has a great service manager.
