Well, it's the second trip I have made to Minnesota and have pretty much gotten stranded. The problem is a horrible misfire that seems to start around the 3 hour mark and keeps getting worse until I can hardly keep a steady 50 mph on the highway. This vr4 is completely stock and I recently replaced the fuel filter and checked the pump sock for dirt. I figured I had the problem fixed because the car seems to run fine when cold. What would get worse and worse with heat? The coil pack? Maybe a bad fuel pump?
