There are many things that could cause this. Overheating, short, bad amp component, bad ground, loose/dirty connections, wire gauge too small, Sub itself, etc, etc.
I would start with the basics. When it stops working does the power light on the amp change color, or as stated above, turn on a protect light? Check your connections, make sure there is a solid ground and also check that the battery terminal is clean with no fuzzy buildup. As a rule of thumb I would make sure the ground wire is the same gauge as the power wire (at least 4 gauge). If all that checks out I would unscrew the sub and check the wiring inside to make sure there is no short inside the box. Otherwise it may just be an old amp that needs replacing.
Good luck, hope you figure it out.
Oh and I have had bad luck with sony amps, even their lower power amps around 500W RMS, the quality is just lacking with the Xplod series. I've seen a brand new xplod amp show massive clipping on my oscilloscope which melted the voice coils on two subs before I checked it out. I would just go straight for a new amp. You can get a decent 500W RMS amp for around $100-$150 brand new that would be much better than what you have now.
