No, I have not replaced the fuses, and that is probably a good idea on general principles, but it is hard to see how a fuse could explain the very consistent stalling at coolant temps below 80C. The fuse might be sesnitive to ambient temps, but not to coolant temps.
But I will put that on my list of things to do for the car anyway, and maybe prevent some other stuff.
