06 636 bog and wont start!!!!

[SIXDIRTYSIX]

ive searched but couldnt really find anything similar, what i got goin on is once i arrive at the lot unload the bike and start it up it sounds like its running off of 3 cyl, then give it about 15 seconds and it works its way out and runs fine! but as im riding if i come around and stall then take off again its got a really bad bog at low rpms, then if i let it sit for awhile (20 min or so) then go to ride again, the bike will just crank over and wont start, i noticed today that when i go to start it the neutral light oil light and fi light come on, when it acts up and wont start the fi light doenst light up at all, im completely stumped on this one, any advice would be much appreciated!!!! thanks
