I am a new member. I would just like to bounce some info off you for a second opinion. I am working on a friends 98 FLHTCUi because of a stalling issue. The stalling occurs in any gear, any speed and will occur as soon as 5 minutes after start up. The bike stalls, no bucking or hesitation....just quits. About two to three seconds before it stalls, the check engine light comes on. During these few seconds, the bike can accelerate normally or cruise without a problem. The engine then just shuts down. To get it started, all I have to do is cycle the ignition or kill switch. I am so used to doing this that I cycle the switch while riding and dont even use the starter unless it stalls at low speed. The check engine light does not stay on after it starts up again. It has stalled up to 15 times on the hwy in less than one mile. Pretty scary when passing someone. I have also ridden for 2 hours without incident. The bike has been to the local dealer and because of its updated computer (previous owner), they can't access scan data or any codes. The sticker on the computer says the data link is no longer operational. Even thou this is a HD computer, the dealer does not have the cable or software needed. Go figure. According to the manual the VAS (vehicle attitude sensor) which is built into the cam sensor will shut the ignition down if the bike tilts below 80 deg. The only way to restart it is to bring the bike upright and cycle the ign or kill switch. I'm pretty certain this is the area of fault but I'm not 100% sure. These sensors are over $250 from hd so I'm wondering if anyone else has run across this problem. Also, is it possible to install a sensor without the VAS? I have checked all grounds and connections. I have swapped relays and updated the circuit breaker. The ignition switch and kill switch have been checked I should also mention that just prior to stalling the tach drops to 0. Sorry for the long post. Thanks......your thoughts?
