Hey guys. I need a little assistance. My 2007 mazdaspeed3 starts up after it sits for a while. It will run for 5-10 min then shut off. If I rev it up too much, after a while it dies. If I put it in gear and try driving, it will die. This all started when I was driving down the road and all of a sudden it slowly lost power and died. It is not throwing any codes. Any suggestions on where to start looking or if anyone has solved this similar issue? I tried searching the web but found no leads. Much appreciated thank you!
