Actually, this has to do with your engine condition lever settings.  If you are using a throttle quad, and you have your engine RPM levers pulled back ANY length at all BELOW the RUN position, this can and WILL happen.

While in the air, you can adjust your feathering, etc. as needed, but the engine condition lever has to be completely forward at LEAST to the RUN position anytime you are on the ground or the engines will essentially cut off (ergo why it says "GROUND STOP").  I will go into the sim immediately and take a screenshot set to show you what I mean.

This is not just an issue with landing.  if you touch that lever at all below the RUN position while you are on the ground, your engines will die and you will have to restart them.  This is proper behavior.

I hope this helps.  Stand by as I will post screenshots showing exactly what I am referring to and how to properly have your controls set while the C-130 is in any operation in which it touches the ground.
