98 115 johnson 60 degree has about 100 hours... Engine started fine, ran at 3500 rpm for 20 minutes then 10 minnute at 1000 rpm. Engine went dead. No spark. Had to be towed in. I tried several times to start with no succsess. Came back 2 days later, engine started right up... Note; on my previous trip I noticed the tachometer dropped out a couple of times, reading 0, for a minute or 2 then came back on without affecting performance while at 3500rpm. I have not experienced starting problems prior to this.<br /><br />Ken
