we were fishing in south dakota the other day, in the morning the truck started fine, went to eat, i let it run and when we headed out of town about 2 miles it quit. it blow the fuse. the dealer started running the codes and tests, about half way though the test, it started and ran fine. they think it could be e.c.m., but do not know for sure. At $700 bucks, its a chance. Any thing like this happen to any one else? Would like to fine out more, i dont like the idea that it could stop at any time. Its run fine for 3 days now. thanks ken
