How does it die?

Is your gearbox in Low?

You need to be more specific if you want a solution to your problem.

it die means it wont move it do like if you put the 5th gear and want to take of and only it do this on sand and on hilly offroad and some times on low range third gear it does the same as like there is no power, but in mud and snow it works fine in high gear , only it moves when i put first gear in low range. and i did overall to the engine to clear this problem but even though still the same problem
