I had similar issues with mine not so long ago, the car would misfire under load, and struggle to start. After many headaches, and replacing the spark plugs, leads and distributor / coil the problem is now gone and turned out to be a drop in voltage coming from the coil (apparently it was stuffed).

It does sound like however there is a voltage spike in there which is blowing the injector fuse, this is likely to be related to the misfire. I'd recommend looking for any shorting out and running a multimeter over the wiring to ensure there is a constant, and steady voltage.
