2001 regal stalls out

So I have been trying to find out what is wrong with this regal and after doing a little searching it seemed it was most likely the crank position sensor causing the problem so that got changed and now the problem isn't so bad but it happened twice in about 30- 40 minutes of driving after the change which was better than it was doing before.
So after reading something else it seems like it is the ignition switch because the second time the starter was not working and after turning the key a couple of times it started again.

So I was wondering how likely is it that it is that switch and worth trying to change it? I do know they had problems with them from around that time because I had a Malibu with a switch problem So it seems that it could be part of the problem.
