hey, i have a 98 cougar 550. i can take it out and ride it for about 15 to 20 minutes it starts fine, idles fine, runs fine after riding a wile it will try to die whenever you are off the throttle. it cuts down to running on just the left cylinder some times it comes out of it right away but most times it goes into it and wont come out of it until it dies. it will not start without sitting for 10 to 15 minutes after that. then it starts and runs fine again until this repeats. does anyone have any ideas? it really feels like its something electrical. but i'm at a total dead end with the thing.
