There are a few basic things.
1. What type of radio gear are you using? If it's 27 or 40 MHz, then you'll have a long antenna on the receiver. Has this been cut, as the length is critical?
2. Is the transmitter antenna connected OK ?
3. Are the batteries in good condition - both Rx and Tx ?
4. Are all connections OK - Sometimes the plugs can loosen in the Rx, with all of the bashing ?
5. Are the servos in good condition ?

If all of the above are acceptable, then it may be that your Rx has been overpowered - being asked to transmit too much power to the servos.
This will require replacing your Rx, but also if the servos are fine, then you can get power bypass wiring that powers the servos directly, and simply uses the 'signal' wire in the Rx.

It may also be that the Rx and / or the servos are operating at a voltage outside the operating range. Have you changed the Rx battery to LiPo - (I have on my MT) ? If you've 'gone LiPo', you must consider a voltage regulator. LRP produce a 10A/6V regulator that is perfect here.

Sometimes, it's where you are operating. If it's near power cables, or where there are automatic doors like at shopping 'malls', these can affect the radio signals.
Generally, it's an opportunity to go to 2.4GHz, as the majority of us have already, which generally eliminates radio problems.

I had similar problem. Actually it leaded runaway..... I had faulty battery. It ran few mins ok and always started cutting just likethat. New battery with good charger (with deltapeak) is always good thing. Actually I think cheap rtr wallchargers will destroy accu sooner or later. Personally I prefer accus with twin connectors, tamiya for charging and basic bec for connecting so I don't have to unconnect anything when charging. And for charging imax b6 has been good and cheap (not usual combination) charger.
