Random warning tone

Hi!
I have an 1987 17' Grumman with an 86 or 87 Mariner 60 HP. During an outing today,(after about 2 hours of run time) a random warning tone came from motor, motor died momentarily, then continued running fine. There is no auto blend hooked up, gas is mixed with quicksilver. The fuel tank was near quarter tank, and I was cutting across a wake at medium speed, so gas in tank was likely sloshing around. Was warning from motor sucking air or water for a second? Water pump replaced last fall, water peeing strong. Manual not very clear on this, and not sure I could repeat it yet! :)

Thanks for any help!
John
 
I've thought about it somewhat...maybe a momentary piece of trash on the water inlet which caused a brief rise in temp to set off the temp alarm.
 
Single beep, long continous beep, multiple beeps??? Or jus I single random?? Loose wire, bad key switch turned off for a sec and reconnected??? there should only be two sensors low oil and overheat and key on test I don't think there Is anything that would kill your engine except key switch
 
Thanks for the replies...
4-5 ringing beeps, not very loud. Water stream died down momentarily (but did not quit altogether) as engine was dieing down, but started back up strong immediately as rpm's came back up. Didn't realize there was a key switch on this motor..no tone when I start it. Boat is my father-in-laws, loaning it to me for season, so I don't know as much about it as I should. He didn't know what the tone was and if it ever did it before...course, he's about deaf, so...LOL
