getting a bad sputter/ what sounds like it's loading up effect with the evo when i roll into boost.

one day the car is right as rain and runs with no issue, il start the car hours later and it pops all over the place and doesnt come out of it. been doing this off and on for awhile now.

replaced plug's
gapped them
replaced coil's
boost leak test
i have a maf i can switch with.
everything is stock, i have my evap system capped off is all.
it's an evo 9 motors w mivec in an 8 body.

any idea's?

 

Fuel cut?

 

idk what would cause fuel cut one time.. but then be fine all day the next day.
