What is wrong with my truck?

What is your question?

My 2016 Chevy Silverado 1500 has just shy of 99,00 miles. Two weeks ago I bought a new 4 year battery and my truck has been starting just fine. Yesterday, I went to start it and just a slight "click." I tried it several times and then it started perfectly, no drag at all. Today the same trouble. I went to town and made several stops BUT it didn't happen everytime, it was intermittent.

What makes this problem better or worse?

It's intermittent, nothing seems to affect it.

How long has your 2016 Chevrolet Silverado 1500 had this problem?

Just a couple days.
