Cost and what is required to replace power steering high pressure hose on 1991 chevy blazer

I recently bought another blazer a 91 4x4 with 4.3. ( apparently i do believe truck sat for at least a few months before buying) I have replaced the fuel filter and put seafoam in the tank. After driving it for around 30 min she starts spittering and sputtering. I've already spent 400 replaceing Alternator and u-joints and few minor repairs. I love blazers i just don't wanna keep spending and still have this problem. The muffler does have a hole in it, could this be cause of problem or should i be looking at something else.
