The #4 fuse blew again and now it blows as soon as I turn on the ignition. If I start the truck and disconnect the positive battery cable, the engine dies. Could it still be the alternator shorting out?

I would check your fuse panel for some of the connections being loose on the back side of it.

Also, don't remove the positive cable when running unless you want to take the chance of blowing your computer.
