So.. its got a
27 Meg radio
Mtroniks ESC
Kondor Motor rated for 4,8 to 12 volts
2 of 6 volt batteries wired in parallel for a long run time.
Any of the Mtroniks ESCs should handle anything that a Kondor can throw at it.  This should eliminate any loading put on by a bad combination of prop, alignment, overtightening things etc.  Is anything hot when you get it back? (thermal shutdown - dont really think its that because the second run would be shorter)
Radio.  When the motor/ESC stops responding, does the rudder still work?  If it does the radio is still working.
The setup should work OK off the main battery just using the ESC BEC to power the RX/servo.  Trying a RX pack might help eliminate a range of problems.
Does the TX indicate anything with the battery LEDs?  If it stops transmitting, the RX will obviously stop receiving.  Of course, there are plenty of other reasons for it to stop receiving - loss of power and a loose crystal being top of the list.

What type of radio set it it e.g. Futaba, Hitec, ACOMS? Some types are prone to limited range.

MTroniks use 5.5v drop-out regulators in their speed controllers, so if your main batteries drop below this then the failsafe will trip. I'd suggest charging up both batteries independently for 24 hours, then try the model using just one of them (i.e. not with two in parallel).

No knowledge of range issues with Hitec Zebra.
Full power = Full load on batteries, which might well drop the voltage below 5.5v et seq. If you have a multimeter then you could monitor the voltage across the batteries at full power to see if this is the problem.
Try the test I suggested above.
Also try disabling the BEC as per MTroniks' manual and using a separate set of batteries for the receiver.

I did have a bit of a hiccup with an Mtroniks ESC - I was trying to set it up to use a more convenient part of the stick travel and the result was that when I turned the wick fully up it stopped.   I put this down to the ESC program which probably has a very definite maximum pulse width, anything more is considered a fault and it shuts down, just in case.  That was my thinking. 
I just re-read the instructions (often a good idea) and set it up again conventionally, no further problems.  I have a choice of makes of 27MHz low price TXs, and it helps to remember which model is set up for which ESC as all seem to have different mid-point settings.

Reset the Mtroniks ESC's they sound like you have got them slightly out of what they like.

Turn trans on ,make sure throttle stick is centered
Switch rec on and hold button in on ESC,
Push stick fully forward then neutral then fully backward then neutral (this sets center off and full each way
repeat for other ESC's

Go to lake have fun fun fun.

Which mtroniks ESC are you using ?
When you first installed the P&P ESC did you make sure that the forward stick push went to the max on you r trans and again for the astern stick push. If by slim chance you did not get the stick fully to its limit and then went to the astern movement the ESC has set itself to have its max at the point the stick stopped, now if you go past that the ESC goes into a dead area type of thing so your model stops until you bring the stick back slightly.

I dont know how to reset that type of ESC. if that is what has happened.
if you have an adjustable transmitter you may be able to alter the % of signal to travel of the stick..
Just a thought

yes that is what happened but dose not happen every time i push stick full speed and as for the stuttring of motor i have  now got the ariel coming up the side of the mast 8 inch then over to the funnel about 6 inch  ran motor for over 2 hrs tx 40 ft away no stuttering or loss of power have same set up  on my badger  same batts same esc but 40 rx tx no problems with that. BUT i was told  the council have laid an electric cable to power the fountain and this could upset 27 mh   where i go. but next time i will go to the other end and see what happens, thanks all  ps i know clear as mud ..
