When I first leave the house everything is fine for about 10 minutes. After driving for a bit I notice the brake pedal starts to get extremely hard and it feels like im driving with the brakes on. The truck will start to slow and when I step on the gas it has a extremely hard time gaining speed. Also normally at a stop when you are in drive the truck would roll forward a bit. When this is happening its a dead stop. Brought it in for service, could not get the truck to do it. Im frustrated.

Good morning,

This sounds like one of the wheels is dragging causing the fluid to heat up and expand. When that happens, the brakes come on gradually until they lock up the wheels.

You need to check each wheel to see if a caliper or wheel cylinder is the one causing the drag. You should find one of the wheels that are not totally free.
