Echo PB-580T Backpack Blower dies after 6 minutes of use

[wsdivall]

I have owned my Echo PB-580T Backpack Blower for 4-5yrs. It's easy to start and starts/runs like it always has. However, it has now started to just die after 5-6 minutes of use. I replaced the carburetor, air-filter, primer bulb, gaskets, all fuel lines, spark plug, and rubber grommet several months back. I have been trying to use it for the past several months with no change. It still dies after 5-6 minutes of use. It was an off-brand carburetor, which I have never had an issue with using on my echo, Honda, and/or Stihl equipment. I just ordered the OEM echo carborator and replaced it. The blower still dies after 5-6 minutes. What am I missing?

It could be the coil. I have seen coils work when cold and quit working when they get warm. I have seen some spark plugs cause a similar issue as well.

Vacuum being created in the fuel tank?

How would I troubleshoot this?

I'll inspect the coil and make sure there are no obstructions. Anyway to test a coil before simply replacing?

I had a PB-255 handheld that was giving similar issues. What spark plug are you using? It should be a BPM8Y or BPMR8Y. Long story short I like someone else mentioned thought it was the ignition coil, tore the entire blower apart, and put a new OEM in it. That didn't change a thing. Got to talking to a friend that is an Echo dealer and he asked what plug was in it, I had a WRS6F, and he told me to change it to what Echo called for and it has been running perfectly since with a BPM8Y plug. Look on your spark plug lead just below the cap, there should be a tag with the plug number.

Buy an inline spark tester and run with that in place. When it dies check for a spark, that will tell you if it is the sign. coil.

Most likely the coil to me . I had a stihl blower do the same . Replaced coil and end of troubles.

I have had coil issues like this. Equipment will run fine for a few minutes and quit. There are tests including
an echo tester that has high praise, but runs $65 so if you don't repair equipment regularly that wouldn't make sense.
Coils are cheap and I have found the after markets work. I replaced a Stihl Blower coil recently. The blower had been discarded
in a junk pile. Works great now.

I see you replaced everything but I don't see you saying you replaced the fuel filter.
