i'm looking at buying a 1995 skidoo summit 2-up w/ reverse. it runs good for about 20 min then it shuts off. the guy thinks that it is something electrical. it has 6000 miles on it and is in good condition besides that. he wants $750 for it. any help would be appreciated.

You need to see if it has spark when it shuts off, then go from there. $750 sounds like a lot for a 13 year old sled with a possible gremlin

I agree, sounds like too much money, especially with that many miles, you can find something nicer for that price
