Need some help. When I get up to highway speeds, 50+ the truck loses power and eventually won't go anymore. I can push the pedal and nothing will happen. After sitting for a couple of minutes I can turn the truck on and I can drive away. If I keep it to around 30mph or so it drives fine. Appreciate the help.

 

Check the turbo for a bad turbine. Could also be a HPOP problem too.

 

Could be a plugged fuel filter. You have 2 of them.

 

Thank you. Turbo seems fine. Any way to test the HPOP without digging it out?

 

Thank you. That would be the easiest. Any way to test that without taking them off?

 

You'll need a scanner, but he goes through how to test it:

 

When was the last time you changed the fuel filters?
