Electrical failure

2001 Chevrolet Blazer 250000 miles
Good afternoon, I would be glad if anyone could help me with my problem. My car had a failure in the fuel pump's fuse, and at the whole fuse box was replaced by a new one. That was the moment when a strange electrical failure appeared. I've already bought three batteries and a whole fuel pump and the problem is still there. It has happened only once that it started and lasted on for an hour and then stalled. I've also changed the coil and the module but it is still failing.

Have you checked the fuel pressure's regulator?

I own a van 1999 and its problem is that, when starting, it won't develop speed. If there is a small climb, it won't advance but stand still. What might it be? I need some advice.
