94 Voyager 3.3 engine

I have a 94 Voyager with 235,000 miles. The 15 Amp engine system fuse blows and motor dies when the it is warm and pulling a moderate load (going up a small hill). I have replaced this car and am planning to give it away but would like to solve the problem before I do. Any thoughts?
