I too had the same problem just recently and it turned out that in my case, the battery connection was not seated in the receiver resulting in a low voltage condition and it was the RX causing the problem not the winch. I did call Futaba and they stated that the "low throttle" (in our case, sheet servo) is a safety measure programmed in the TX. Check your Futaba manual.
There is also a voltage regulator in the winch which I bypassed by using the "Alternate Connections" wiring shown in the RMG winch manual. This bypasses the internal winch regulator so you don't have to worry about that cutting out at low voltage. I did not install a separate winch switch but wired with only the RX switch in the circuit. As an added precaution, cycle your batteries and make sure it is not the cause of your problem.
As an aside, this past Sunday at the Palm Beach Gardens Regatta, I started having rudder problems. By a process of elimination, it turned out to be a bad pot (potentiometer) in the TX. My TX is only a year and a month old and I'm hoping they don't charge for replacement. The way you check for a faulty pot is to move the sticks slowly and observe if there is any jumping or hesitation in movement. It should be absolutely smooth movement. To be sure it's the pot and not the servo, connect the servo to another channel and observe if the condition persists.
Also, check out RMG'S info at the Electronics folder under "Experimental findings, current draw.

I've been having an issue with my 6EX apparently going into failsafe mode. I notice this problem when on a run and all of a sudden my sails are pulled in from full out. I can immediately reset by going to low throttle position on the transmitter and then back to high and everything works fine again.
I'm using a 7.2V battery so it's not battery failsafe or lack of voltage. During these incidents the rudder remains useable and I'm having this problem at what I consider very close range (less than 100 ft at times).
I've looked over everything and don't see what could be causing the problem. Is anyone else having this difficulty?
