I found a 2000 D2 on craigslist pretty cheap but the seller says it will randomly die while driving. The said it will go a few days with no problems at all then out of nowhere the engine will die while driving. They said once it does die if you let it sit for a couple of min it will start up and drive fine. Without first hand experience behind the wheel what do you more experienced rover owners think it could be? I was thinking crank sensor or fuel pump.

 

Sounds like the crankshaft sensor to me too... http://www.roverparts.com/Parts/ERR7354G.cfm

 

Looks like a fairly simple repair if it is the crank sensor. Now I just need someone to buy my M3 so I can get another D2.

 

Yup, bad crank sensor.
If you can get the truck cheap enough go for it man!!
