There are a number of things that can cause this however, I have seen this a number of times. The issue is most likely a driver circuit that is shorted, and it only turns on when cranking the engine or it is running.
This means it is either a coil, injector, or even a starter.
So, the most likely of these is a coil. I would suggest disconnecting the coils one at a time and crank the engine. When the fuse stops blowing then that is the problem coil.
Here is a guide that will help with this testing as well:

Next, we need to do the same thing with the injectors. If all this checks out, we can move onto the starter.
However, please let me know what you find. Thanks
