Is there any model in simulink that can block the data input in a specific time to create a fault condition. For example, I need to block 30 seconds of data in a 10 minutes dataset to creata a fault condition

When you say "block the data" what do you mean? Should the data change to 0's or NaN's?

You can use "Switch" blocks change your signal from whatever it is to a constant 0 using the time as a determining factor.
Alternatively you can use "Matlab Function" block where inputs would be time and the signal and output will be determined with an if statement with in;
function y = blockSignal(t,x)
if t > 10 && t < 20
y = 0;
else
y = x;
end
end
