On a side note - If you replaced the battery, did you get it tested at the same place you bought it?

And, cleaning the cables may not be enough. There may be internal corrosion that decreases current-carrying capacity that you cannot reach. We have members who had to replace their battery cables to resolve the problem.

There, that'* seven!

To properly test a battery, you need to put it under a heavy known resistance load and watch what happens to the voltage over a period of time. Most auto parts stores, and any good shop will have this type of battery tester. The parts stores will test your battery for free. You can buy a load tester at harbor freight tools for about $15.

This was me too, on literally every Pontiac I've ever owned:
1974 Ventura
1978 Bonneville
1988 Grand Prix SE
1997 Bonneville SE
2001 Grand Prix GT

If you are planning to replace your battery cables, I do recommend you buy the actual factory cables from a GM dealer. Be aware they will be fairly expensive, as far as cables go.

Default Newbie has same problem

I've got a 92 Bonneville, and similar symptoms... Car dies will driving it, for no good reason; battery seems okay, wait five mins, car starts again, drive 15 mins, car dies again.. Now, after a week of no driving, car won't turn over, won't click, won't do anything. Thanks to this post, I will begin by checking the corrosion on my battery cables. Thanks!

It that doesn't work, I'd suggest that you start a new thread so your problem gets the attention that it deserves. Also, welcome to the Bonneville Club.
