    Like I said runs for about 15 mins then dies. Won't start for about 5 min then when it does 15 mins later it dies again. The longer ride the shorter time it takes to die. Please help

    could be quite a few things, we need your help to narrow it down. Is it fuel or electrical related?
    When it dies do you still have spark at the plugs? Carry a spare with you and when it dies hook it up to a plug wire and lay it on the engine, spark or no spark?
    Could be fuel system problems, partially clogged lines or valves making flow to the carbs slow.
    Have you upgraded the fuse box yet? Might be losing power to the TCI when everything gets to operating temp.

    Just throwing it out there, but it could be old/not enough oil.

    Could be all sorts of things, up to and including TIGHT VALVES. But let's not jump ahead.

    We need a whole lot more info to be able to help; beginning with:

    -What bike?
    -Miles on it?
    -Your history with it.
    -Has it ever run correctly?

    Plus the answers to mlew's questions.
