seems to me you neglected to reinstall the ground cable body (to the eng.) possibly?
What did the 'new' engine come out of?
I hope you bought the alternators from auto zone or something and are getting them replaced under the lifetime warranty...
This is what I would do... remove the battery cable from the battery after you shut of everything in the car... lights blower fan et al... and see if you are getting an arc when you reattach it. That will give you a clue to whether a dead short is involved (if it arcs strong ) .
if you only get a spark it is normal , as there are draws that you can't dislocate w/o removing fuses.
If you dont get the dead short arc , then put a lead on the - NEG. post and ground the neg. to the engine dirrectly from the battery to any bolt on the engine bigger than 10mm. ( a bracket or the instilation hooks on the eng. should give you a reliable ground. if that causes an arc while the car is running my first thought is correct.
The lack of a good solid ground to the engine will cause the stalling out due to the numerous electrical componants that do thier job via variations in voltage. This voltage is measured in very small incriments,
and any deviation from set limits will cause your engine to run poorly.
It is my assumption that your battery starts the car , then the sole source of electric is being drawn from the altenater .

If you purchased an aftermarket altinater they can be bad. I have had bad ones before. Pull positive post off battery and keep it off for about 30 seconds to a minute. Reattach the cable and see what happens. This resets the computer. have the altinater checked but not at Schucks or the warehouse parts stores. Find a Napa as they seem to have the best testers and altinaters.

Couple of things to check, first this may be nothing more than a belt that has loosened or stretched after the install.There should only be about a quarter of an inch stretch in the belt between pulleys. Caution - only check with engine stopped!!! The alternator causes a strong resistance when it is producing electric power, so slippage is to be checked first. Second, if the battery light comes on and off; it maybe acting in error. Get a multi-meter and check the battery voltage with car and ignition shut off. With the meter set on 12volt bat, place the black probe on the negative side of battery or ground and the red probe on the positive side of battery. If you get a reading of 12.66 v the battery is being charged and is full. If you get 12.45 you have a 50% charged battery. If less the alternator wiring needs further checking into as there maybe issues with wiring or the alternator itself. Hope this helps.

If you have an Auto Zone store near you have them test your charging system they will do this FREE of charge and tell you if it is the battery or alternator. If you do not live near this auto parts store check with one that is near you and they will probably do the same for you. Good Luck With This
