Misfire/rough idle/cutting off

I have a 2007 Chevrolet Silverado 1500 4.8L.

I have replaced throttle body, spark plugs, coils, camshaft and crankshaft sensor, mass airflow sensor and my vehicle still has a misfire on cylinder 8 and skips. After running for 10 mins it cuts off. What else can I do?

you really shot the parts shotgun at this one.

Did you try any troubleshooting like measuring fuel pressure?

Get it scanned for codes to find out what's really going on.  Then go from there.  Everything you did hasn't solved the problem and cost a lot.

Well it wasn’t that expensive, but it’s at the mechanics now.
