Has anything been checked,tested or replaced for this issue here at all?

Does it start eventually or do you have to jump start it?
Are any other electronics acting up with this issue here?
O.k.,is it acting up now to do some testing at all?
O.k.,the most common cause for a no crank no start issue when no other electronics are acting up is the starter itself.Even if there isnt a click from the starter the starter can be at fault.The other issue is the electronic ignition switch but usually this will cause faults with other electronics as well if this is the cause here.
Locate the starter relay in the under hood fuse box (labeled start or crank) and when this occurs if this relay clicks when trying to start the vehicle then the ignition switch is o.k. and the starter needs replaced most likely.You can test the small purple wire at the starter for power when it will not start when the relay clicks and if there is power then the starter needs replaced.
If there is no click from the relay at all when this occurs then try tapping on the relay and if it starts then,then this relay needs replaced.If it does not start then the ignition switch is the most likely cause needing replaced.The signals would need to be tested at this relay to be sure.
