As the title states, I put in a new battery but it won’t run consistently. It runs for the first five minutes or so and then stops. I’ve tested multiple batteries (already ensured the correct battery number) and they’re all good. Any suggestions? Thanks in advance.

If you don't have a full function quartz tester you won't know what the problem is unless it's obvious.
About $20 for a new complete movement.

I know what I'd be doing.

So now the watch runs for about 11 or so hours before stopping. I continually go back and wind. It forward a bit and reset it. Wondering if I can just change out just one part instead of the whole movement.

Nobody repairs quartz movements! Replace it! No such thing as replacing “one part”! It is the total over all condition of the movement that is the problem. NOT the condition of one part!
