Should I replace the fuel pump?
My car stalls on hard stops when the gas tank is less than 1/2 full. I'm thinking of dropping the gas tank and replacing the strainer.
Any reason not to replace the fuel pump too while I'm at it? It works fine now but it'* 11 years old. And yes I have run it down below 1/4 tank quite a bit.

Bill you are a posting machine!
A new pump can certainly be worked into the budget... see my last post re: 7 months severance pay.
You're right, I definitely don't want to do this job twice!

I would do it. I just replaced mine because the car has 120k on it now and I wasn't sure if it was the original pump or not. Just a little extra insurance I guess. Of course, a new pump could die just as easily I suppose, but the odds are lower

tank
Check your gas cap if it is venting properly.
There should be no difference in pump performance between 1/2 and full tank
as the filter sock is at the bottom and totally submerged.
Have you checked pressure at the fuel rail? Changed the filter?
Adding mystery oil to the tank will dissolve any rust and sediment in the filter
sock and lubricate the pump.
Water in the fuel could also cause this.

With 1/2 tank of gas the strainer is usually submerged and works fine, but I suspect under heavy braking the gas is shifting around in the tank. I'm not familiar enough with the layout of a gas tank to know exactly what'* going on. But there is a TSB regarding this condition and the solution is to update to the newer strainer.
The problem has been happening since last summer. I changed the fuel filter last fall. I added a couple of cans of dry gas this winter. Problem persists.
Mystery oil is an interesting idea, what brand do you use? Marvels?

maybe you'll get lucky and the fuel strainer just fell off, like mine did
