AFTER I RUN MY DIAMO VELOCITY 50 FOR A LITTLE WHILE IT STARTS CUTTING BACK ON ME. I'VE CHANGED THE GAS 2 TIMES.I'VE TAKEN THE INTANK FILTER OUT AND IT LOOKS GOOD. THE PUMP PUMPS GAS WHEN I TAK

Hi, Check fuel pump that it is running properly. Sounds like an electrical problem with the pump. Good luck.

maybe it didnt run out of gas but just shut down, if it did run out it may have sucked up dirt from the botoom of the tank causing the fuelpump to lock up, what you can try to see if the pump starts again is to spray starting fluid into throtle body and cranking the engine, the engine should start and will die out after fluid is burnt but may stay running if power stays to pump and it frees up, you may have to try this a few times, if you spray and it doesnt start then you may have a diffrent problem. make sure to have someone hold pedal to floor and spray for 3sec, then release gas pedal connect hose to throtlebody and try to start. good day.

Take a look at this tip I wrote on the no start problem. It should help you.
