"Basketball Wives" star Evelyn Lozada is giving show producers an ultimatum -- either pay her $20,000 an episode ... or she's gone for good.
As we previously reported, Lozada has already threatened to leave the show -- after, we're told. she became upset because she believes the producers of the show leaked sensitive information about her to another cast member in hopes of inciting a violent confrontation between the two women.

Sources close to the production tell TMZ, Lozada and the other girls currently pull in around $7,500 an episode -- which means Lozada's latest demand would mean a SERIOUS raise.

No word yet on the show's next move.
