early morning , what time does it open ??? thought of giving them a visit.

wut car u send ?

i suspect its your coil.
btw check also your spark plugs ,battery cables etc

yup distributor coil. but normally if its distributor coil even when the engine is idling theres constant jerking to the engine.
if its just on start-up might be your battery terminal , cables , spark plug etc. but since you mention its all new an okay.
quite a headache also.
btw to check whether its your alternator that needs changing , start the car and unplug the negative terminal if the car is running straight without dying then you have a good alternator. if its not then time to replace or refurbish (**beware that this method some say would cause damage to modern car ECU, though personally ive tried it on a couple of my cars and it seems okay without any problem). the normal safe and easy method have to use voltmeter

thats one honest wireman seriously.
people like this are slowly but surely dying in this world.sad thing
