I had the same thing happen to me with a f2504x4 with the 360 engine. it was brand new and fouled plugs like crazy. I took it to the dealer at least a dozen times without resolving the problem. then a sharp mechanic warmed it up for an extended time then pressurized the cylinder and found the head had a small pinhole from the casting process. this leaked oil into the cylinder when hot and fouled the plug. a possibility with your situation???
