I have a 99 rodeo and it runs wonderfull when it is cold, but once it gets warm about ten to fifteen minutes of running the # 5 cly quits fireing, it's not the coil, new plugs the red and yellow wire stops putting out any voltage. I have traced the wire throught the loom back into the harness and cannt find any problems.
I have talked to a few people and I am running out of options on what it could be. any help would be wonderfull
thank you

 

I take it that no one has any ideas?. if you can please help
