I too have this problem. When car shuts down, the windows do not work, nor does the drivers seat controls work. I replaced the fuel pump thinking the lack of fuel was the cause but was wrong. I found out today that 1995 through 2001 gm has problems with the ignition switch. Apparently a slight jar to the car while driving, not always picked up by the driver, causes the old switch to jiggle thereby losing the electrical connection to the fuel pump, windows, and driver seat controls. I am going to replace that this weekend and clean the buss as shown in thread #45. Cut and paste this link in your browser select your year and check your vin # to see which switch you need: http://www.autopartswarehouse.com/search/?Ntt=pontiac+bonneville+ignition+switch- &...
I hope this helps you and will repost to let you know if it did or did not help me.

Thanks for your reply. Apparently I am having a slightly different issue than you are. My seat control and windows work fine here. This thing just doesn't want to start. Everything seems fine electrically here, security light goes out like it is supposed to as well. (thought this might be the issue but it doesn't seem to be.)
I really am running out of options. I would agree, with you except for the fact that everything else seems to be fine.

My 95 would start then 1 sec later it would shut off . I found that the security system would not send the signal to the ECM to enable the fuel injection. Check Autozone.com for ECM diagram and http://www.bakerelectronix.com/ . You can replace the BCM/security system or order the part from bakerelectronix.for about $50 with shipping

I have a 97 Bonneville SE that is now giving me problems. A couple of weeks ago I started haveing problems with the car dieing at both hwy speeds and idling. It finally dies and I found the crank sensor was bad. After replacing that I now have a new issue, when I try to crank the engine the starter will engage for about a quarter to a half turn of the engine then it will disengage and the starter spins freelly. If I release the key and try it again it will repeat the problem. I replaced the Solonoide yesterday and am still haveing the same problem, although it will sometimes spin the engine enough to get it started. Any ideas what could cuase this?

Did your '95 bonnie just die suddenlly? It may be the Crankshaft senser, mine had the same problem a few weeks ago. Now I just have this starter issue to deal with.

Have you checked for spark? Can you feel the injectors snapping to inject while the car is being cranked?

If it will run while you spray fuel into the intake, then you have shown that the problem is the injection system. It is not operation.
I don't know whether it's a sensor? camshaft sensor? PCM control for the injectors? that's at fault. I don't have a service manual for a 1995. If you send an email to my carspace email here I can tell you where you might get help.
