Our Wrangler performed beautifully in a recent 4-day, 550km offroad rally. We went over and through nonstop dirt, sand, ruts, bumps, rocks, creeks and logs. However, the next day, while about 50km into the drive to the airport, going smoothly at about 70km/hr, it completely stalled. We could not re-start it (engine was cranking) and we had to tow it home, but the next day, it started.
Twice since then, we have not been able to start it, once after it had been sitting all day (but had run just fine earlier) and once after a long morning running errands. In both cases, after a long wait (2 hours), we were able to start it.
I was able to get the electronic trouble code P0455, an evaporative emission control system leak detected. We do have a non-Jeep locking gas cap, but have had it for a long time without this problem. I am thinking maybe there is a problem with one of the hoses.
There is not a reliable Jeep repair shop here in Suriname so we are on our own to try to determine the problem and order the parts to fix it ourselves. I am just wondering if anyone else may have had a problem like this or can suggest a solution.
