I am lost for words for my lawn mower. I have replaced the spark plug, oil, the cold start push button. I can get it to start and run for about a minute or two at a high idle, then it dies and will not start no matter what I try to get it to start. I tried adjusting the idle but nothing has worked past the initial start up. What is wrong with my lawn mower or has it passed on to the pasture.

I forgot to add it is a Craftsmen 6.25 Hp model 917387440

Hi,
Try a #399188 needle and seat in the carb attached to the float.
Peace,
