Are you sure it wasn't "it sounds like you are losing me"?  If that's the case, then the person who said that was most likely telling a story or explaining something to someone, but then they realized the other person wasn't not understanding them.  

For example, if I'm talking to you in English and you have a confused look on your face and I can tell you aren't understanding what I'm saying anymore, I can say "it look like I'm losing you."  :)

How sure are you that it was the word ¨loosing?¨  I do not think that is a word.  We have ¨loose¨ or ¨losing¨ and I have even heard ¨loosening,¨ but never loosing.

She might have said ¨sounds like you are losing me.¨ If so it would depend on context.  Sometimes people say ¨you are losing me¨ when you are talking and they are having difficulty following (understanding) what you are saying.  In a relationship that is going bad, someone could potentially say ¨seems like you are losing me.¨ 

Thanks everyone! I believe I had understood the meaning, and surely it was a typo, it was 'losing on me'. and yeah, given the context I believe Susan and Kristal have nailed it. :)
