Default 2005 Sonata 2.4l dies semi-randomly.

I bought this 2005 2.4L with only 101k. Other then needing a Timing Belt it ran great. I drive Uber BTW..

So I replaced the Timing and Balance shaft belt off Amazon first thing. Then discovered the CPS was falling apart. So that was added.

A few months later the CPS died, and I was able to get it in. Without removing the timing belt, on the side of the road. This time it was a Lifetime warranty part from O'Reilly's.

Then the car randomly died while drive a customer. No codes!!

Then again.. however it didn't happen with the A/C running..

I replaced the Throttle position sensor, and re-soldered most of the Body Computer which fixed the Dash Lighter socket, and the Dome light.

Then it happened again.. this time with more fuel. So I replaces the fuel pump.

I cleaned ALL of the Grounds I could find.

Then I re-soldered the Body PC.,.. Now the ECU (by the fues box). Which calmed a 75mph vibration oddly.

Yet it's still dying randomly, and I still can't find the dash boards common ground! The A/C always resolves the issue.

Does anyone have any ideas on how to resolve this??
