2003 Johnson Suzuki stops few seconds after start

[alex191]

Please help me to diagnose the problem. The motor was running fine until lately. It starts a little hard and shuts few seconds after start. Also tachometer repeats turn on cycle after start (lights and one beep). I did replace spark plugs and hi and low pressure filters. I also clean idle control valve with engine intake cleaner. What else may cause a problem? Anyone had similar problem?

Anyone??

sounds like 12 volt power is dropping off causing motor to die and then gauges come back on.
Check all battery cables and connections
then other connections if problem is not found

My Suzuki DT140 needs the resistor plugs to run. I see you changed plugs but not sure if you changed them before or after your trouble. The wrong plugs cost me a fishing trip last summer. I'll never forget that lesson.
