About a month ago I started noticing my truck wanted to turn over longer than normal before it would crank. Sometimes it fires right up, but a lot of times struggles. Went to go crank it recently and it would not start, only turned over on and on. Found that the fuel relay fuse had burned out, so I replaced it, and the truck fired up, and didn't have any issues it seemed. Now it is back to struggling to crank again. Any ideas what could be causing this, and what would have caused that fuse to blow? Truck only has 58k miles, new battery and spark plugs. Thanks for any input you guys can give.

That part is a kit with instructions on how to perform the fuse relocation. The original fuse #27 in the battery junction box cannot handle the load so they came up with the relocation to a cartridge fuse that can handle the load.
