Answer
Hi Luis,

      Intermittant problems like yours are tough to diagnos in a forum like this. The way to approach this would be to first check the fuses...which you have done...and any power wires and grounds that you can find. Haveing a wireing diagram is also very helpful because when the problem acts up that is when you need to get out your voltmeter and see where you are loseing power. For example the problem might be with a maxi fuse so when the radio quits you would check for power with your voltmeter at the radio fuse and find none. Looking at the wireing diagram the next easiest place to check for power might be at the maxi fuse. If no power there then you will need to keep traceing the circuit. Or if you have power maybe the problem is a loose ground wire under the dash. You would need to trace the ground wire in the same manor until you found a loose bolt or connector.

    Hope that gives you a start on how to check. Bill
