Good Afternoon. Mercury 40hp 1990 engine running strong for 45 min, stalls a little bit and after 1 min stops. After 15 min starts again, runs good for another 20 min. I anchored the boat for 30 mins and engine did not turn on at all. Next day I noticed the 20amp fuse was blown out. Replaced it and engines turned on fine in back yard. After a week, tried again but engine did not turn on at all. <br />Thanks for you help.
