Disclaimer: I am not a teacher, but
pardon Sirs, may I give my two cents.
(1) "I lost contact with her ever since we left school." should read as
"I have lost contact with her ever since we left school". The use of "present perfect" means that starting from the moment you left school, you have lost the contact of her up to the moment you talk about this. If "the past tense" was used, it would mean that the loss of contact was a mere past event and no longer existed. As such, You might have resumed contact with her.

(2)"I lose contact with her ever since we left school."
In this example, the use of "lose" (the present tense) with a since-clause is basically wrong, as the present tense is only applicable to siutations like permanent truth, facts, habits.
