@drockz40 has the engine compartment got wet . do you wash your engine ? Has the truck been in flooded area ? your question is rather vague and a little difficult to understand. So lets start here " truck stalls and wont start when I get gas" by get gas to you mean pull up to the pumps and fuel up the truck or do you mean it stalls when you try to accelerate , increase your speed ? If its after filling the truck it could be vapor lock caused by poor tank ventilation . a vacuum is created in the tank that is strong enough to stop the flow of fuel out of the tank . If this is the case the there will be an evap code in the obdII system . Have the codes read and see if there's a code to help direct you to an answer. If the problem is with acceleration and stalling out once again we need the codes read to determine whats going on as there are too many possible thing that can cause this . map sensor , oxygen sensors , maf sensor , fuel filter , air filter , fuel pump fuel regulator , fuel lines . any one of these can cause the car to stall . Then you mentioned lights and stereo not working right . these problems can be caused by a wet computer connection that has started to corrode . This is why I asked about the wet engine compartment . We'd love to help aand if you can share a little more info it would help
