If i was to place a big isolator on the positive battery lead of the winch to the battery is there possibilty of voltage lose??? The main reason for this is for safety.

You could definitely have a big-ass isolator close to the battery on the positive cable of your winch. One day you could hit something or somehow damage the cable and if it isn't isolated, it could cause a serious short including possibly a small explosion, which could also include blasting acid all over your engine bay.
Provided the isolator is rated for the level of current your winch will draw, there will be no loss of voltage as a result of having it in the circuit.
Normally this would mean using quite a grunty isolator as your winch could draw several hundred amps of current.

Yes, I was reading that.
The only reason an isolator would be a problem is that it's not rated to enough current. If you get a strong enough isolator it's a good thing to have for safety reasons imho.
The one I originally pasted in above was the wrong example (I am going to delete it in a sec), but something like this one:
is good for 250A continuous or 2500A for 5 seconds and that should be enough for most winches judging from the specs I have seen.
This one is the same rating but double pole, so you could use both poles in parallel and effectively get double that current rating.
Or there's this beauty
which is rated to 500A continuous, 2500A for 15 seconds, and a winch pulling more than 500A would be very rare. A switch this sturdy would probably be overkill.
I honestly don't see any reason why using a really heavy duty isolator like one of these would cause any voltage drop or other problems. My guess is that people having problems used switches that were too small.
Of course these are manual isolators; if you were talking about some kind of automatic cut-out then it will probably be harder to find something suitable.
On the other hand these things can get a bit pricey so they may or may not be worth it to when as someone said, you can put a wing nut on the terminal for relatively quick disconnection anyway.
