I have a 2003 4 stroke 115 on my pontoon and it won't start. Put the boat in Saturday and cranked and cranked for 25 minutes. Put back on trailer pulled out of water opened cowl started and put back in the water. Drove for 20 minutes no problem brought to my dock, shut off and restarted immediately. Went back down to the dock 2 hours later won't start. Next day won't start. Took cowl off cranked motor with screwdriver in plug wire to test for spark and engine started. Shut it off and put plug wire on covered it up went for an hour ride. Returned to dock started back up. I Next morning won't start. Bypassed lanyard,etc. Boat only has 142 hours.
 
Don't know much about those 4 Sts but maybe you got a pack going bad ? When it won't start check your spark. See if it will jump a 3/8 " open air gap.
