I've had some poor cranking problems on my V70. I have had the starter/solenoid replaced and also the P-N-P switch.

Now it starts perfectly every time when cold and runs great cold or warm.

Only issue is once hot, it sometimes won't crank at all or if I let it cool a little bit it will crack really slowly and eventually start.

I know the battery is not the issue because it starts cold every morning with no issue and is only two years old. I could take it to an indy to load test the battery just to rule it out for sure.

Wondering what else could be the issue? Sounds electrical related.
