Hey all my car shut off again and it restarted again after about 1 minute...the thing is ..i felt like it was going to do it today..it quirked a couple of times today just slight ones that i could barely feel in the gas pedal....but as i was driving going about 65 mph i heard something like a hiss like something came on or went off..3 minutes later i heard it again..3 seconds later the car went dead...from sitting on the inside of the car..the sound seemed to come from my right hand side but in the rear...i am not sure where the fuel pump is..but as you know the filler is on the opposite side..any suggestions would be freat thanks.!

Do you have any electrical problems, like flickering lights or the radio forgetting its time?

We might need a new set of codes.

Does it shut off as if you turned the key off? If so, my '95 was doing this soon after I bought it (used). It turned out to the the crankshaft position sensor. No problems since replacement. A buddy had an earlier Bonneville ('90?) that did the same thing and was fixed by the same fix. Good luck.

When was the last time you cleaned your bat cables and posts?? Could be just corrosion on the post and or cable.
