Keep blowing MPI fuse..

[4g63tcrazy]

Well recently my car started blowing the MPI fuse.. It happens about every 2-3 days. Also one thing I noticed which I think might be contributing to it is one of my injectors (1600's) Keeps getting stuck closed every once in awhile while I'm cruising on the freeway and it'll misfire on and off for a bit. But then it will clear up and be fine again. Would this cause the MPI fuse to blow? Or would it most likely be a wire shorting out? The fuse started blowing more often as the misfiring kept getting worse. I'll more then likely have the injectors sent out to get cleaned and flow tested.
