The car just loses power and has a hard time staying running when this happens. Changed the crankshaft position sensor but it still is acting the same. What else could be causing this?

It sounds like you have a fuel pump that is going out. Do you have a check engine light on? If so lets run the codes to get an idea of what is going on.

Here is a guide to help you get started:
