I have a 2000 Isuzu rodeo, 3.2 6 cylinder. It will run or idle for a short time, then it will rev up really high, at the same time all interior lights and gauges shut down. Then within a couple minutes, it stalls. When I go to start again, it needs to be jumped. I was told it could be the throttle position sensor, but I'd like to know a little more before buying unnecessary parts.
