Alright fellas any ideas? When I just drive around town ,my truck is fine. but when Ive been driving for bout a hour or so straight my truck acts like Ive taken my foot off the accelerator when I havent and I start to lose speed. Weird thing is that my RPMs stay the same place that they were it just dosent take the power to the wheels. Itll only do it for about 6or7 sec then it will catch and I will catch back up on speed, til it does it again bout 5 min later. Any ideas????

 

Possibly a clogged fuel filter or a blocked fuel cap vent or a worn out fuel pump or none of those.

 

yea but I would think that would cause the RPM's to drop which they are not, they stay steady but i lose speed

 

maybe your clutch is slipping when it gets hot?

 

That makes more sense
