Truck will deacclerate happens 3 or 4 times in a row. . Like you took your foot of the gas but you haven't moved the accelerator. Will resume speed by itself. Only lasts a fraction of a second. only happens after you have drove 3 or 4 hours. will happen then drive normally for half hour or hour. Doesn't happen if you are driving less than an hour. Seem to be worse if you have the cruise on and driving more than 100 km/hr ( 60 miles/hr) seems to stop if you are under 80 km/hr ( 50 mph) No codes show up. I have changed spark plug, ignition wires. timing chain, fuel filter. Mechanics have checked the sensors and they are all fine. Have taken into shop 3 times. 2 times to Toyota. no luck on solution.
