Something tells me the problem may be with the coolant temp sensor of any other temperature sensors that may be there. Are you getting correct reading from the thermometer on the dash?
The fuel pump is one of the most reliable parts in the vehicle, if your van drives fine, the pump should be fine.
If the engine misfired, there should be error codes that can be read with an OBD II sensor. Those are cheap, you can buy your own from ebay and read the codes yourself. It always helps to know the codes before asking in the forums as the codes can be specific, though some codes may be pretty vague.
