After starting my Craftsman generator, it will run for (exactly) 60 seconds then just dies, it does not sputter like it is running out of gas, it just shuts off. After a few minutes, I'll restart it, and it'll run for 10 seconds and dies again, this will repeat until I quit trying to start it. I have pulled the gas line, thinking it was a clogged line; it's not, I cleaned the bowl, tried carb cleaner, it still does the same thing. What is the cause of this?

What engine do you have ,
Check for a oil shut off.
Check oil.
Luck

Yep, low oil safety would be my first spot to check, look for a small red light.

It is the 7 hp. Checked the oil, its full, when it dies the low level light does not inuminate at all-american not even a flicker.

Not sure why my phone auto corrected "all" to all-american"??

OK, I have by-passed the problem. As read on a previous question, it is the oil low pressure sending unit. I disconnected the wire from it and it fired right up and kept right on running. Just wondering it I should spend the $$ on a new one or just leave it as is?

I would not fix it, just keep an eye on your oil. I own at least 20 engine power pieces of equipment and only my generator has the low oil switch, interesting.
