A problem

For which pairs (G,M), where G is a non-abelian simple group and M a maximal subgroup of G, is the following true?

For any element g outside M, there exists h in M such that g and h generate G.
This is true for all maximals if G is PSL(2,7) or PSL(2,11), and fails only for the smallest maximal if G is PSL(2,q) for q=5, 8, 9, or 13.

Old problems are kept here.
