    If you found cold solder joints (open spaces) then yes, they need to be reheated with a 25 Watt soldering iron. Too much heat could cause a solder run whereby the lead composition spreads to associated components and causes a short circuit or burns out vital parts. Remember, if a board shows any sign of stress it can break or slightly crack at other points along the way. Usually, it is best to replace the defective board with a factory replacement if it is a reasonable solution.

There is a short on the video controller and when it heats up, the circuit opens and disconnects or what we call a short circuit. A technician can locate that point with his/her test equipment and do a repiair.

Sounds like your fuel pressure regulator. Check vacuum connection at fuel pressure regulator. That's the only easy check. the rest may have to be trial and error, i.e replacing fuel pressure regulator and then fuel pump if that doesn't work.

I looked it up and it sounds like your unit is defective. It should run for 5, 10, 15, or 30 minutes. There are no "seconds" options. The timer chip/module may be defective.

SOUNDS LIKE A COLD SOLDER JOINT OR A BAD COMPONENT WHEN IT WARMS UP THATS WHEN IT STARTS ..TAKE OFF THE COVER SO THAT YOU CAN SEE THE SOLDER SIDE OF THE BOARD PUT POWER TO THE RADIO AND WHEN IT WARMS UP AND SHUTS DOWN TAKE A LITTLE PIECE OF WOOD OR PLASTIC AND PROBE ALL THE SOLDER CONNECTIONS TO CHECK FOR A COLD SOLDER JOINT IT MAY BE GRAY IN COLOR MAY NOT.. SEE IF IT GOES ON AND OFF.. IF SO RESOLDER THAT SOLDER JOINT.......IF THIS DOES NOT WORK ....PICK UP SOME FREEZE SPRAY AND SPRAY IT ON THE COMPONENT'S ON THE OTHER SIDE OF THE BOARD THIS IS WHAT A SERVICE PLACE WILL DO IF THAT DOES NOT WORK NOW BRING IT TO A SERVICE AND LET THEM SCRATCH THERE HEAD GOOD LUCK
