Why does my weedeater start then it just stops running

change the fuel filter and check the fuel pressure

I would replace the so called spider fuel injection assembly, it is known cause of this complaint. See photo

CHANGE FUEL FILTER AND CHECK FUEL PRESSURE.SOUND LIKE FUEL PUMP FAILING OR FUEL PUMP RELAY BAD.

Hello, I have 1996 Ciera with rebuilt engine pretty new, also fuel filter and fuel pump replaced but I have a problem, the car starts and runs well cold but once car has been running for a few hours, either stopping or coming to a stop it starts to idle roughly and has come to a stop at different occasions. Check engine light does come on and off occasionally. Can you help?

Sometimes a rough idle like that is a fuel filter. As you've already done the plugs and wires the fuel filter would be my next bet.

usually when the camaro runs rough that could be bad fuel injectors-o2sensor and fuel filter-thats my guess i had the same problem and i put bad gas in and the fuel filter went bad

You say you replaced the fuel pump, what about the filter? If the filter is clogged it can cause this as can ignition. Since the car started for you after the fuel pump was changed the original problem was the fuel pump. But you should never change the pump without installing a new filter.

I have a ryobi doule line bought in 1997..Had same problem put new gas cap on and problem solved..could not get air in....

Stihl weedeater was running and stopped suddenly. Put in a new fuel filter and cleaner air filter with soap and water. Checked spark plug and it appeared fine. Started the weedeater, ran for a second or so and stopped. Spark plug wasn't gas fouled. Could it be the carburetor needing new diaphram gasket and spring.
