Djokovic was leading by a set and serving at 2-3 when he was forced to save two break points.
But on the third break chance for the German, Djokovic looked to be in charge of the point after pushing Kohlschreiber wide and approached the net for a high volley.
However, Djokovic inexplicably put the backhand volley wide to gift the break and put Kohlschreiber 2-4 ahead.
Djokovic then smashed his Head racket three times on the court and received a chorus of boos from the spectators.
Amazon Prime commentator Mark Petchey said: “Wow. When he does break it, he does break it with a little bit of venom and passion.
“And you can understand.
“It was by his standards, a fairly routine volley, although under pressure down break point.
Petchey’s co-commentator Sam Smith added: “It just shows you how tightly wired he is.
“There can’t have been any impact from his early losses in Indian Wells and Miami.
“Confidence, it takes a long time to build up.
“You can lose it in a heartbeat. You really can.”
Djokovic did break Kohlschreiber straight back and they exchanged two more breaks before the German broke the world No 1 again and won the second set 6-4 to take the match into a deciding set.
The display of anger from Djokovic resembled scenes from last month in Indian Wells.
On that occasion, Djokovic and his doubles partner Fabio Fognini failed to break opponents Jean-Julien Rojer and Horia Tecau and he took his frustrations out on the back fence.
Djokovic threw his racket at the back fence so hard it left a visible hole in it.
