Once you have ridden on a square taper crank that is not perfectly tight, the taper will be damaged and it is very hard to get them to stay on. You can tighten the bolts as hard as you can and it will still loosen off.
Some people have had luck with filing the taper down, others have used shims made from alloy can.
