90 vert starts and runs fine at cold start. After it is warmed up, if it is stopped for more than 5 min. it will then start fine but but be in "limp mode". Doesn't matter if it has been running 15 min. or 2 hours. Has that characteristic roll from 1000 rpm to 2500 rpm when ya hold part throttle and wont go over about 2000, 2500 rpm. Never does it cold, nearly always does it hot. So far have always been able to restart with out limp after 5 -15 minutes of restarts and/or leavin it idle in limp. No engine light so assume that means there is no code to pull. Very, very frustrating. Starts fine every morning and every evening after work, but don't even try and stop on the way cause it will then start in "limp"
