I have a Homelite UT32600 26cc string trimmer. The problem is that it just stops running after about 5-10 minutes of use. I've replaced the fuel pickup/filter, fuel lines, carburetor, spark plug, fuel cap, and muffler/spark arrestor. The carb adjustments seem to be correct when it is running. No problems starting initially and it will restart after a couple of minutes but will stop fairly soon afterwards. Any ideas?

Could be losing spark, bad ignition coils sometimes provide the symptom you have. You'd have to test spark with a proper spark tester (not a spark plug) immediately upon it dying, or run it with an in-line tester with an LED.

Thanks, I'll look into that. I was wondering if that could be the case since about everything else has been replaced.
