Today for the first time, I was at idle for 15 minutes and the engine died. No codes or CE light. Nothing on the auto gauge as well. Restart was perfectly normal, and it did it again.
It also died while driving at constant 25 mph. Popped it into neutral and it started back up.

1999 4.0 auto stock engine and tranny/tcase

What should I start checking?

Thanks.
 
Battery connections first, then the CPS. IAC may be sticking in the throttle body. Get an OBD-II scan for any pending codes too.
 
Thank you. I have an ultraguage setup and there are not current or pending codes. Ill get a new cps tomorrow. Maybe have it installed at tech day.
Dealer part or vato zone
 
Most people recommend the dealer CPS.
 
Let's hope it is a permanent fix!
