welcome aboard,<br />could be fuel related, could be spark...<br />(assuming it's not overheating)<br />start by getting a manual if you don't already<br />have one (bottom of this page or library)<br />have you done any maint. to the motor?<br />does the primer bulb stay hard? have someone<br />pump primer bulb when she starts to die and see<br />if it picks up again.<br />good luck,<br />M.Y.

Like trhe other gentleman said could be fuel or spark.I had the same problem with mine,the primebulb was old and weathered bad. I replaced the primebulb and now it runs great.hopefully yours will have the same problem,because Wal-Mart has replacement bulbs for about 9 bucks.Good luck
