Well, got the genny running by gravity feeding gas (had to literally
fill the hose with gas before it would fire and then it would just
consume the gas in the hose and then die). I also gave the fuel pump a
good wack. I don't know if that helped but it felt good. Starts right
up, we'll see if it does so in the morning too. ...

Just a thought...
Why did smacking the fuel pump help?
A normal problem with these pumps is lack of use. The fuel in the pump evaporates and leaves a film (varnish) on all the parts. The internal parts are a metal slug (aka Piston) and a check valve. They could be gummed up fairly good with varnish. Smacking it will loosen the parts and allow them to work. But unless you use it very often (running solvent (fuel) through it), it will gum back up rather quickly.
SO... To make it reliable, clean it or use it!
It is fairly easy to clean.
