Ok, I'm actually posting on behalf of my fiance's mother. She has a 2000 Jeep Wrangler inline 6 I guess. Has the hard top. Manual transmission. I dont know what else. (I do not know much about Wranglers, I'm a muscle car guy). Anyway, for whatever reason her Wrangler will suddenly begin to gradually lose power and shut off for no apparent reason, while she's driving. After sitting for a few moments it will start up. I checked the alternator, battery, and starter. All are fine. My guess is a wiring problem, but I do not know. I'm not good at wiring. Even though she plans on getting a new Wrangler soon, I wanna get this fixed because Im probally getting the thing from her because I've always wanted one. So I figure I would be helping myself down the road by helping her now. She also says that sometimes when driving over really bumpy areas, the lights on the dash begin to randomly light up and act funny (like the battery light, check engine, etc...) Was wondering if this sounds like a common problem that these vehicles have that you all might be aware of. Any and all advice is greatly appreciated. Thankyou.
