Playing Ahead of the beat

Thanks, guys... I do not have trouble playing in time with everything. I have the most problems playing in time with lead whether it is improv over a blues backing track or trying to learn a solo from a song. I tend to rush the beat. I have learnt several rhythms and do not see the same problem in my recording. Well at first I do but eventually get the kinks worked out and it sounds fine. I just haven't seemed to lick the problem with solos and improv.
