Onan 5500 Generator Wont Stay Running

2015 Fuzion 371
After it starts it will only run about 1-2 minutes then chokes itself off. Float bowl still has full once it dies also. This is what i have done so far
Cleaned the carb jets / they weren't dirty / float working
Checked fuel filter for clogged / its free
Loosened gas cap to check for vacuum free tank
Fuel pump is running during priming
Checked fuel pump is pumping fuel / instant full when activated
Oil level is at recommended mark 2/3 full
New mother board installed last year
Not showing any codes
Fuel tank full / fuel flowing from line no restrictions

Any ideas are open right now Thanks

Lots of tiny passages in the carb. I’m thinking carb is bad.
