My 850 2010 xp efi will run good then just sitting for a few minutes it wonts to shut off like it ran outta fuel then it will finally crank back anybody might know or have any ideas please thanks

 

Couple things I'd do off hand. Change plugs.Other than a battery plugs are one of the most over looked parts.May be as simple as that. If that doesn't help then check fuel pressure. Should hold 39 psi +/- 2 psi. If fuel pressure checks out and still dies,could be a t-map connector or wiring harness problem that's plagued a lot of efi machines.
