I have a Johnson2001 130HP Ocean Pro with about 8 hour's on it. The problem is when its at full throttle for about 15 seconds it drops idle and dies out. It takes about 5 minutes to start. When its in neutral after it starts it runs strong give it gas in neutral it sounds powerful like nothings wrong . in gear at a low throttle its fine when I open it up she goes 15 seconds later while the throttle is still open the RPM'S drop and she dies out. Any help please. Thanks
