I have a 1999 suzuki DF70. last fishing trip the motor when to 3000 rpm's and I can't find the reason. I changed the fuel lines, pump ball, water separator, rebuilt the low pressure pump, new high pressure pump, sent fuel injectors out to be cleaned, have 40 pounds of fuel pressure, new spark plugs,new thermostat, new water pump,new batteries, new oil and filter, get no codes on tachometer, did test all the manual said to test, dealer loaned new computer to try and it ran the same,,need new idea to try ,, thanks
