it turns off when the engine is running.
most likely its a bad spark plug or Ignition Coil No. 3.
if you have not replaced the spark plugs start with that.
if that not not fix the issue, there are two coil packs
1. is for spark plug 1 and 4
2. is for spark plug 2 and 3
replace the ignition coil that shows 2 and 3 on it (see picture below)
