IP Primer pump or lift pump concerns

I have a new style primer pump on my IP and noticed that it was hard to push down.

It gave quite a bit of resistance before I finally was able to push it down. Once I did get it to push down, it had no resistance at all but it didn't seem to pump at all.
The reason I was checking it was the car had stalled out on me and I couldn't get it to restart. It just lost power and sputtered out on me. I was thinking that it got fuel starved but the filters were full.
I was able to get it restart after putting a fresh charge on the battery. It seemed to run fine but I didn't want to drive it risking getting stranded again until I figure what could have caused it in the first place.
I'm thinking either the primer pump is going out or something in the lift pump is sticking. I leaning toward something in the lift pump is the issue since I don't think the primer pump would cause a loss of power and stalling.
What do you guys think?
