mine has a similar issue as well..
when i start it up after leaving it overnight or after more then 30minutes, its struggles to start unless i step on the accelerator to give it some help..
if i dont step on the accelerator, it just cracks, starts up for a split second and turns off
but if i just stopped driving, turn it off and start it again 5-10mins later it starts up fine, what could my issue be??
