2014 Tundra V8

last week my Tundra did not want to go over 60 on a flat highway then next time I drove it it started fine drove 15 miles or less parked it 20min later it did not want to start then it started and died let it set 20min again and it started up drove fine made it home shut it off then started it a couple times and no problems.

 

Fuel pump? Is your truck flex fuel?

 

Mileage?

 

I agree with @Joe333x it sounds like a fueling problem. I'd have the battery and alternator tested 1st though, our trucks are super sensitive to voltage changes.

 

@ZappBrannigan The mileage is a little over 116,000
@Joe333x I am not sure if its flex fuel. But I did open the hood to check the fuel pump relays and I noticed that there was only one fuel pump relay. Could that be the problem?
