Recently purchased this from a gold mine. It’s starts perfectly fine. Drive it up a hill or for longer than 5 min consecutively (in high or low) and the power steering light will either flicker or be solid red. I lose power steering and all power in the engine. Sometimes when I let off the gas and it revs down the light will shut off but if I accelerate any, the light will come back on. Other times it’ll just sputter and the engine will die. I checked all fuses (power steering and general) and they look fine. After I bought it I replaced the spark plugs, air filter and element filter thing, changed the engine oil and both transmission oil things (front and back). I have an hunting trip coming up and can’t get it into a mechanic before… Any ideas?
