I wonder if it is a combination of poor rooting and drying out, I doubt string sun helps as they are woodland plants.

I love gooseberries! Our climate is pretty similar, although I don't think we reach 100F most summers. Ribes are not going to be impressed with -10F that is nothing for them. The heat is a stress.
I've been propagating two cultivars pixwell and captivator. The Captivators do well in clay (since that is all we have). They will take a couple years to get going. The main issue here has been moisture. They need good moisture the first year or two, and a summer drought makes them lose their foliage and a few died. The second year they had much more growth. The other issue I had was that they are a major japanese beetle forage, and recovered very poorly from it. I put in some bluebird houses and quit mowing short and they did much better. They are in a mix of sun and shade, and doing fine either, but they have pretty thick mulch in the sun.
The Invicta gooseberries had some mildew, new last year too early to propagate. They are a newer one i am trying. Pixwell did not do well but I am trying it in some other places. The clear winner so far is captivator.
