New York was called for all three penalties in the first period, on undisciplined infractions for elbowing, cross-checking and high-sticking.
The Lightning went 2 for 6 on the power play, and New York failed to score on its one chance.
Kucherov also scored from the left circle 3 minutes after Stamkos' goal to make it 2-0. Victor Hedman got his 188th career assist to become the franchise leader for defensemen.
Halak was pulled and replaced by Thomas Greiss 2:50 into the second after Johnson scored from the left circle on Tampa Bay's fourth power play. Halak allowed three goals on 16 shots.
Shortly after Vasilevskiy made a strong save on Casey Cizikas during a 4-on-1, Ladd pulled New York to 3-1 midway through the second.
Boyle scored early in the third.
