I would guess it would be fuel related, check your fuel pressure at fuel pump and see what's up.or the dealer will figure it out for you since you have 20 miles on it.
I let it sit for two hours after pulling it in to trailer to haul back to dealer and the thing started rite up .Ran around for a while runs perfect WTF.It was low on gas but not empty .
Sounds like the pickups are rearing there ugly heads again. Been a major PITA since these machines came out. It's not a backfire but rather no fire cause the front pickup will not stop sucking and sucks up air effectively cutting off the fuel to the motor. My sled ran fine the first season but after sitting and then riding this season I had to pull the pickup and fuel pump assembly and switch the front non vented smart valve (pickup) with one on the back that was vented. Go to HCS they have a sticky with pictures in the Turbo forum. Old problem and an easy fix just takes time.
