Build a Website - Database

I have a WordPress based website, and every time I try to upload the large 150,000 entry database .csv file it stops uploading after about 30-40k entries. I have tried using various plugins such as Sabai Directory, WP Business Directory, I have changed the configuration on my servers, and tried 3 different servers. Not sure what the problem is. Need a absolute WordPress expert. Please have passed either your WordPress exam or your PHP exam. I need this done today.
