400ex not getting fuel to cylinder or past spark plug

I have a 440ex with the following Uni,velocity intake, 150main 42 pilot, 440 big bore and a dmc afterburner quiet exhaust. I was riding on the street the other day and I was braking from about 50mph 5th gear and just started dieing then it wouldn’t start without being pull started but then wouldn’t stay running at low speed. I got home and found that I was getting feel to the carb but pulled the plug and it was dry and not colored so put a new plug and nothing any help? Oh and I have no kill switch
