Ok, so I've got a 1994 Ford ranger, 3.0L V6 and I've got a really wierd problem. After driving it for about 30 minutes, all of the gauges on the dash will drop to zero, all the dash lights will come on, the gas petal will freeze up/go stiff, and the steering will lock up. The truck will stall, and some times the power stays on on the dash, and sometimes it won't. Now, the engine runs like a champ, but it does have a lot of miles. Some times it will start right back up and run mint, and sometimes it needs to sit for 10 minutes before it'll start up. Now, If already replaced the ignition switch thinking that the contacts were expanding when the switch heated up, but it's still doing the same thing. I'm not sure were to go from here, because its gotta be some sort of electrical problem, but I'm not sure what, maybe the PCM? I don't know. Any of you ace mechanics got any ideas? Thanks.
