Star guard Luka Doncic scored 26 points and Dorian Finney-Smith added 24 for Dallas, AFP reported.
Devin Booker led the Suns with 35 points. Jae Crowder added 15 and Deandre Ayton scored 14.
The Philadelphia 76ers also won a second straight game at home to level their Eastern Conference series with Miami at two-all.
Former NBA MVP James Harden scored 31 points to lead six Philadelphia players in double figures in a 116-108 victory.
Center Joel Embiid, who missed the first two games with a concussion and facial fracture, scored 24 points, his presence again making things tougher for Miami defensively.
"The organization on offense, it helps a lot with him on the floor," said Philadelphia's Danny Green, who made three three-pointers on the way to 11 points. "Without him we look a little discombobulated."
Harden also pulled down seven rebounds and handed out nine assists in his strongest showing of these playoffs.
