Using power windows shuts down engine

Using power windows shuts down engine
1994 Bonneville SE 182K miles. Periodically when I hit either of the front door'* power window button, the engine dies. Immediately following, it will crank over, but won't start (the windows never stop working). If it sits sometimes 5 minutes, sometimes 30, it will start and run fine. If I immediately hit the window button again it normally dies, but not every time. When I'm trying to restart it, I don't think I can hear the fuel pump turn on. The last time it happened I noticed the fuel pump running right before it restarted. This is my everyday driver, but this only happens periodically. On average, I'd say once a week.

NExt check the battery connections especially the positive cables if there are two positive cables with one on top of the other. Check for corrosion between them. Also you might check the cable down from the battery for corrosion; you might slice into the plastic to take a look at it.
The next place to check would be the ground bus connection that is at the bottom of the a pillar where the bundle of wires runs under the door sill area. There is a ground bus on both sides of the car.
Before disconnecting the battery turn off all accessories including the AC unit so it cycles off. Some people have had problems with their auto HVAC units after disconnecting batteries for replacement.

I agree to check the ground buss. I believe the fuel pump is grounded out there also. If there is any corrosion there, the extra draw from the window motor could make the entire buss lose contact.

I had same problem before I found this site and replaced a lot of things that were good. Clean all grounds under the hood, in the cabin , battery connections and the ground buss. Good luck!

I went through something like that with my 96. Found a thread on here titled Ground Buss Corrosion. I cleaned the ground buss and it took care of it. Still have another issue but not sure if it is related. Hope this works for you. Just do a search for the thread Ground buss corrosion.
