2015 yfz450r idle issues

i have a 2015 yfz450r
bike has a vortex, barkers exhaust.
it has an idle issue, when bike is first started it will idle fine for about 30 seconds , after that it will die. after that it will not start with out giving it throttle. if you give it throttle itíll run, bike runs completely fine when in the throttle, once at idle itíll die. sometimes itíll do it other times it wonít. not sure where to go with this. any suggestions?

So others can help you you need to give more info. Has it ever worked before with said mods? Spark plug is it original assembly line plug?

2018 YFZ450R SE : warning labels removed, TMD case saver, GYTR aluminum frame skid with the bracket mod, thick helicopter tape here and there, some stickers, everything else stock stock stock like the dealer likes it.
PIN IT PIN IT !!! SCREW BREAK IN STEPS.

On deck.circle: VORTEX ECU/PEAK RACING MOUNT - YOSHI SLIP ON NO SPARKY.

Have you pulled out the fuel pump and looked to see if the pickup filter appears to be free of junk? Pump sounds strong when 1st turned on? Stock fuel cap with stock vent hose? Or those shorty ones with aluminim valve things?
