1/2 mile from home and my brakes went hard as a rock what now powermaster? I hope not what do you think!!

Check the fluid level in the master cylinder. Mine was really picky and liked to be completely full. I actually ended up switching to vacuum brakes yesterday however.

I had a blown fuse I replaced it and now the motor runs all the time

Don't let the motor run more than 20 seconds. You will burn it up if you do.

When the motor is running, do you see the fluid moving in the ps of the bowl? If so, you are most likely internally leaking. To confirm it, get a peice of clear vynl tubing that fits snugly in the ps rear port of the bowl and turn on the motor. If the fluid runs up the tube, you are internally leaking and it's time for a new P/M.

If you find it is NOT internally leaking, I can only guesses from my keyboard that the relay is fused closed and not shutting off the motor. The pressure switch could be bad also. Only way to test it is with a known good one or a new one.
