2001 challenger 2000

so I decided to purchase a 2001 Sea Doo Challenger 2000. I had it on the water Friday pulling a tube around and it ran really well. Took it out again today pulling a tube around and it would randomly cut out while driving. It would start right back up again, but I’m curious what might be...

Any advice, is this boat worth my money, or is it not worth $9,500 for a 20 year old boat? Seller claims it starts and runs well. Body and seats look near immaculate (for a 20 year old boat there’s minimal fading and scratches). Thanks in advance!
