2004 Range Rover won't start consistently

What is your question?

2004 Range Rover is not starting consistently. We've tried a few things to troubleshoot but aren't sure what to do next. If we pull Fuse 18 and put back, the car starts. If we pull the key out the car then does not start. The other thing we've done is in the steering column hot wire the blue wire to the ECU. The car starts. If the key is out the car for a little while (15-20 mins) the care does not start. Battery tested and charged. Alternator tested and good. Thanks in advance, Jeff
