1999 triumph trophy it runs fine when first crank it up . then you go down the road and it justs died let it sit for a min. then it will crank right back up and do it again . i have put a new battery on it help

suck the vacum pipe on the fuel tap to let fuel into carbs

It could be any of a dozen problems, but it sounds like that year old fuel pump. It could be a loose wire killing the pump or even vapor lock. I would start with testing the pump under pressure.

change the fuel filter, sounds like its clogged up..

my 1st guess wd. be crank sensor

Sounds like you need a fuel pump. There is an access panel in the floor of the car to get to the pump.

fuel tap filter gummed up,lack of fuel?

a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

Hi and welcome to FixYa,

To my knowledge, most bikes of this class would exhibit the problem you posted if they have loose/faulty:

• RUN or KILL engine switch;
• side stand switch;
• or as the mechanic thinks, the CDI.

You can try and verify by simulating the first two possibilities by riding on a straight road at regular speed and with no traffic.

• Accelerate as you normally would then switch off the RUN; do the same for the side stand, even a slight extend from rest position would kill the engine.

I doubt if it is fuel related as normally, there would be hesitation and starvation before finally stalling.

Good luck and Thank you for using FixYa. Happy Holidays.
