Not sure but some lathes have a shear pin on the lead screw. If it's slipping and or jerky in the movement it may be there.

Thanks but I have found that the only time it hangs up is upon starting and when the left selector is in the "A" position.
Otherwise it works just fine.
I am wondering if perhaps there is a piece of swarf jammed in one of the gear teeth.

My gearbox is open on the bottom. With a mirror and a flash light I could even count all the teeth on the gears.
You may be able to see in before tearing into it.

If 
your head is over one of the screws for the gearbox it is most likely a 10" Lathe. The 9" does not cover the screws as in newer 2 lever gear boxes. This pic is from a 9". If I remember the star wheel is adjustable for turning the feed on or off if that is your problem.
