Truck won't start.

My truck is a 1993 Nissan pick up, it has just under 175000 km's on it and it's a 2.4 L. When I bought it, it was running great and nothing happened one day as I was going down a hill my engine shut off I made it into a parking lot and couldn't start it again.I tried alot of things but nothing would work I looked at my fuses and the 10A fuse for the fuel pump was blown I replaced that and it worked fine.A couple of weeks went by no problem then as I was at a friends house it happened again.I went through 8 of the 10A fuses before I pumped hard on the gas heared a weird squealing sound but it worked fine for a few more weeks. The about 2 days ago I was on my way to a friends and it stopped 10 feet from his house it took two more fuses to get it up and running but by the time I shifted into 2nd to gear down it stuttered and shut off. Now it won't fire up but it does turn over and everytime it blows one of the 10A fuel pump fuse's. I replaced the fuel filter and still nothing? Could it be the wiring in the fuel pump or the sending unit? I really need a lot of help please lol
