Sounds like you have a regulator that needs rebuilt. Or at least taken apart and cleaned.

im gonna try that today

Check that the fuel tank vent is working.

one of the first things i did was pop the tank cap off while it was low on the gauge
and no difference

IF the tank vent were to be the problem that gauge would have shot right back up, wouldnt it?

Open to out of the box? Slap an ice pack wrap around the suspect component. Maybe it can help isolate a heating up issue.

thats not a bad idea
ive wrapped things in cardboard to help pinpoint an oil leak before, so why not?

ill rebuild/clean/inspect the regulator and if the issue persist ill try the ice pack
