Honda 919 EFI Shut down while riding

hey all I was riding my 919 on the highway and the red light came on the dash and the motor shut down. When I go to start the bike the Fuel is not being sent to the fuel injectors. I have a PC3 installed. Never had this problem and the Honda has only 20K original adult ridden miles. Never beat on or abused. There is oil in crankcase. I did not get a chance to plug back into oem connections on ECU. Before I go in over my head has anybody experienced this and can give me a heads up on what to check to hopefully save troubleshooting ? I will be on the phome tommorow with dynojet. My PC3 was bench tested by manufacturer and I bought it new. I can see the unit boot up when I turn on key and everything on bike electric works except for EFI ? I am stumped. The harley guys were scratching their heads when they saw a honda roadside and down.

First things first, remove the PCIII and see what happens.

After paying 100 dollars for a cab ride home. I came back with my trailer and got my 919 home. The next day I removed the oem cpu connector and noticed the black wire with white stripe was severed completely cut in half from those connectors that dynojet give you so you don't have to cut into harness. How redundant. Don't trust these connectors. A few hard bumps pressing on both sides of this connector will work like scissors. Its very scary when your motor shuts down on the highway. Lucky for me it happened right before the rest area so I rolled right in just like a harley. Man am I lucky. I am very grateful. So this error was due to dyno jet connectors. The PC3 is old with too many connections. The PC5 is the way to go. If we get enough requests to dynojet they will make a PC5 for the 9ers. Not flaming or blaming. The failure had nothing to do with Honda. I am grateful I own the best made motorcycle hands down. Honda truly is the shiznitz.

Well done on the fix mate. I spliced and soldered that connection. When I was having cold start issues I contacted Dynajet about the pc5 for the 919. I was told it would be easy to retrofit a pc5 to the 919.
I agree this bike is a honda legend.

I went down in traffic once because someone decided to ride a bicycle thru heavy traffic without looking. For some reason, the bike wouldn't start. I think it's a fuel pump tip over shut off thing or something got knocked around.

I simple test light would have helped me, but I had to get it towed because I couldn't figure it out on the spot.

Maybe we need an app that goes thru the check list flow chart.

Happened to me the first time the bike tipped over on me. I turned the bike off and back on again and it worked fine

It was a few years back, so I'm fuzzy on what the solution was. I disconnected the battery and pulled fuses, etc... but something tells me that the engine kill switch was hit and I didn't bother checking it. TBH, I never use the engine kill switch.

There should be a flow chart of how to run down the process.
