weird stalling

if i've stalled 3 times in the past week or two, and the first two times were while shifting into reverse, and just today it stalled while taking a corner really, really fast, would that be able to exclude any of the million things that make a car stall? oh and the first two times, i turned the ignition, and it was fine, today, however, i tried a few times, wouldn't turn over, got out to look at the engine, couldn't see anything looking suspect (although i don't konw what the hell i was looking for). got back in car and started fine. my battery terminals are kinda corroded, gonna go clean them w/ wire brush /baking soda solution
