Hi, don't get it for granted but to me it sounds the clutch...

When moving from stop the clutch needs to operate at its full potential, when the car is moving already even a quarter of it would do.

Is yours automatic or manual?

I am no expert and I know little about gear boxes but on automatic gearboxes the clutch is a component like "torque converter system"  which includes more parts and that all together connects the engine with the transmission.

On manual ones it could be the clutch master and/or slave cylinder ( it comes as a set) that does not allow the bearing to fully depress.

 

Hope it helped.
