Over this past weekend motor started acting up. Would crank up great and run fine most of the morning. Made a run about 20 minutes, started idling a bit and the motor just shut off. No alarms or nothing. Tried to crank back and would spin about 2 or 3 times and nothing. The top 3 lights on the system check gauge would light up but no alarms. It would start back up after 15-30 minutes but died again few more times. Hooked up the laptop with the diags and no codes. I'm going to replace the water/separator filter and see what happens. Thoughts?
