Because google is constantly crawling website from time to time....That's why your website is sometimes in rank sometimes none... It is because there many competitive keywords right there, crawled by google.... I suggest link to related sites with higher PR and submit your sites to directories with high PR... Wait and see the results...By the way you domain is 3 years old? Change your contents from time to time...
The results needs time to stable. If you change content, the site can be recalculated and revaluated... just wait a moment.
changes in your site ranking and number of backlinks is normal because they uses different datacenter which result to display different results.
