I’d test it first, look for a broken ground wire, if you find it has ground then change the MAP sensor

if you clean it , spray it with sensor safe MAF spray , other stuff can cause corrosion

From what I've read on using carb cleaner, it leaves a residue that coats the heated element, causing the element to burn out.
I have found nothing that states it's corrosive.

Carb cleaner contains toluene a solvent which is harmful if inhaled and as stated in this, it will damage sensors and catalytic converters

so no corrosive but a solvent.

OK, I replaced the MAP sensor and she ran fine for ~7 minutes b4 shutting down with no CEL light. I started it up again and she ran for another minute b4 again dying with No CEL I'm going to clean the throttle assembly next to see if that helps. Earlier posts asked why I randomly changed out sensors and/or solenoids. I was trying to trigger a error code which is the most frustrating part of this problem. After it died the last time, I started it again but had to feather the throttle to keep it running. Finally it gave me a loss of power warning but not a sustained error code.

I'm beginning to think it might be the ECU malfunctioning as I'm not getting any error codes. She runs fine every time I hard boot the system then shuts down like the key was turned off. No sputtering or anything, just off!

If you wanted to trigger a code, why not just disconnect the MAF? No codes means the computers are good; there are codes for malfunctioning computers.

Did you ever think "fuel pump relay" or "fuel pump"?

It won't run smooth with the MAF disconnected! It acts like something is getting hot to cause it to shutdown. It could be the fuel pump relay but the hard boot will cause it to run smooth again. I'll swap it out and do a test run. Thanks!
