Does anyone have a well point well they put in and have attached to an electric pump? And does the electric pump overcome how much water can be drawn out of the ground? Does the pump run dry regularly? Is this normal or should the well point not run out of water if properly in the water table?

Too many variables and unknowns to answer that. You would need to install the wellpoint or drill a well, pump it, and determine recharge rate (the rate at which draw exceeds recharge), and which varies by location.  An electric pump can easily exceed the amount of water available.  You need to size the pump (draw) to be less than the recharge rate or you will damage both your pump (most pumps are not designed to run dry) and likely your well (sides may collapse). Pumps are available that will draw 1GPM all the way up to huge GPM amounts.  A good starting point would be a 3 or 5GPM pump, as that is about what is needed to serve a small household with minimal water needs.  If your well output is less than that, there are accommodations, but optimally 5GPM would be a sweet spot to start with.  Flow rates can vary from well to well depending on what is below the surface too. You might have a good flowing well that is right next to one that barely flows or is dry.
