If that's ok you need to check vacuum on the suction side of the pump...should see 12+ inches of vac while cranking with your gauge on the suction side and the other side open.
If that's ok hook up the suction side and crank til you get fuel, then hook your pressure gauge to the carb side of the pump and crank it... looking for 2-6 lbs of pressure.
If you can suck fuel with a hose and the pump fails either vac or pressure tests,it's bad.
Oh...make sure the tank vent is working!

Thank you for the reply Terry. I just was driving it up and down my driveway to try and duplicate the problem, sure enough it stalled again. As it was stalling I was able to look at the fuel filter and it did not appear to be pumping. After it stalled I pulled the tank line off from the fuel pump and hooked up my brake bleeder. It took a few pumps but gas started to flow out of the line. I hooked it back up and it started right up. I need to get a vacuum gauge and perform your other tests. I guess it’s either a fuel tank full of crap, even though it looked ok to me when I inspected it, or a bad ( new) fuel pump. I’ll do the vacuum test and report back. Oh and I also blew out the vent line and it is clear
Thank you again
