I good friend of mine is having trouble with his v6 dieing while driving. When the truck slows to 52mph, it starts back(5 speed). Any advise???

 

Maybe fuel filter, pump, pressure causing not enough fuel when needed the most?

 

Like stated above, check fuel. Also check all the basics, fuel, spark, could you be more specific on what is wrong? It starts back from being dead? Does he still have all the lights on the dash on when this happens? Any funny sounds? Slows to 52 isn't really slowing up. The more you could tell us the more we can help.

 

Must feed the chipmunks more. LOL

X2 on the fuel filter, also check the injectors, maybe a plugged up catalytic converter.

 

This truck has had the FULL tuneup. He has tried everything, even had the computer rebuilt. It has shown a speed sencer code but the autoparts stores say it does not have one on it.

 

Obviously not, since something isn't working right. Also, the TPS could be on its way out?
