Im having random fuel delivery failure while riding. It last for less than a second and the onset is very random. When it cuts out the fuel light and check engine light come on for about 3 seconds. It happens at random RPM and throttle. Over the last year I have replaced spark plugs, voltage regulator, stator. I did not notice any issues after everything was installed but then about 2 months later it started. I have tried a new fuel pump and ran fuel treatment to try and clean the fuel system with no success. Any ideas?

It could be the fuel couplers the valves in side get worn and they do leak as well some times which means they suck air .... just a thought !

If the fuel pump relay and/or wiring circuit has an intermittent fault this could happen. The fuel pump is briefly without supply voltage. Or, if the ECU signal to control
the fuel pump is intermittent.

Check all of the ground connections you can locate especially the wiring connections around fuel pump relay, fuel pump,ect. Good luck.

Perhaps the vacuum hoses around the intakes???
My girls ran like CRAP after setting up for a few months-- hard to start once started wouldnt STAY running misfiring -- I tried several things till I was fiddling around with the tank off and noticed one of the MANY little vacuum tubes at the rear of the three intakes (there are a BUNCH of them) had dry rotted at the connection --- then I moved it and one of the others damn near disintegrated in my hand-------its a wonder the thing ran at all the week before!!!!!!!!!!!!
turned out a couple hours of doing contortions with my fingers -- 2 Aleve---and some fresh rubber from the auto parts store and BANG ON runs like a new bike!

Most of the times its something simple just like those vacuum lines!
