2.3L ('02-'11) Truck shuts down after a drive

[vantez]

Hey guys I’m new to TRS. I decided to finally join after not being able to find a similar thread with the same issue I’m running into.

2001 Ranger 2.3l Duratec Manual Transmission
200k miles on dash

For the past couple months, when I get home from work and I’m parking the truck, it will randomly just shut off.
At first I thought it was bc I had 3 engine codes:
P1537- Intake Manifold Runner Control Stuck Open (Bank 1)
P0141-02 Sensor Heater Circuit (Bank 1 Sensor 2)
P0171-System Too Lean Bank 1

Long story short the truck had been tampered with before me so I decided to replaced the intake manifold with the originally IMRC valves, I replaced the whole engine harness since the wiring had also been messed with, and I installed an OEM catalytic converter from another Ranger.
Check engine lights went away and it’s been running good for the most part, BUT it still shuts down when I get home from work while I’m parking.

At this point I’m starting to think it’s temperature related, I live in TX and it’s currently summertime.
It’s strange because for my Morning commute, when I’m parking at work, it doesn’t shut off.
But when I go home (95+degF) it shuts off while I’m parking.

I have replaced every engine sensor along with purge valve and vacuum hoses. I even put a mechanical thermostat from TRQ because the electronic one was always getting stuck closed. I bypassed the CEL by bridging a 1.5kohm resister on the connector.

I’m just lost at this point and hoping someone can help.

1st Welcome to TheRangerStation family.

I'm just a novice around here.
However let's go back to the basics here.

Have you double and triple checked all your connectors to make sure everything is connected properly.

When you was redoing connectors did you clean these connection point and use dielectric grease?

Have you tried wiggling wires around to see if you have a short somewhere?

Sometimes having a short that only shorts out when moved a certain way can cause big problems making you think it's other stuff.

If you do have a short the way the truck moves over the terrain at your house when you're parking may make the short, short out therefore cutting the truck off.

Once we know the answers to all that we can move on to other stuff.

I wish you good luck.
And hope you can have fun with your truck soon.

What kinda engine temperature are you seeing when does it? Only while parking at home is odd. What if you pull up at a nearby store after work? Does it sputter a couple times first or just like you turned the key off? Will it start back? If so does it take longer than normal?

That all of the relevant questions I can think off...
