03' Super duty warm up issues

Each day I first start my truck it takes a while to warm up. It won't warn up by itself, i have to drive it to warm it up. In the dead of summer in Florida I can let it idle for 15 minutes get in it and no matter how much gas I give it, the acceleration slowly builds out of first gear into second then third and so on. After it has accelerated through all the gears it is fine until the next day. Some say filters, injectors or whatever but that seems like BS. If after the first mile it accelerates fine for the rest of the day no matter how many times it's shut off, then when left off overnight or off longer than 10 hours it starts again, I can't imagine it to be a mechanical problem but more of an electrical problem. Any help or similar experiences would be appreciated.

    I have the exact same problem. Even when I floor it, the max speed I can get is about 20 mph -- until it warms up. Once it does, I can drive all day without problems.

You probably have an air leak in the fuel line. Air bubbles rise to the top-most area of the tubing and form a "vapor lock" . Find the leak, stop the problem! IT's probably a loose connection somewhere.

Tow/haul light comes on gauge shows HOT

Does the trans fluid have a burnt smell and is it brown or dark brown as opposed to a red wine color? If this is the case then you may have a service issue caused by a clogged trans filter which is what this sounds a great deal like and the sooner you get the truck to the dealer or your mechanic the better as the trans in these are not cheap to rebuild or replace.

F350 super duty,engine cuts out without warning

Check to see if your truck was recalled for a faulty cam shaft sensor. Some sensors develop hair line cracks which allow contaminants to get in and the sensor becomes intermittent. The symptoms can include sudden shutdown of the engine so a recall was issued.
