It is not that Your KMT is not active anymore. He is just too stress up. Give him 2 weeks of rest. Some time humans need to take MC too.
Just continue offering incense, don't ask 4D yet for 2 weeks.. or You can ask but don't expect for any good 4D results... give Your KMT sometime to recover.
You remember when You were young and parents keep forcing You to get good results in Your studies? And then You got fed up and stress up and You become worse in the results.
