So, I took my truck in and the mechanic had a hard time diagnosing what was the problem as he doesn't see a lot of mitsubishi engines these days.
It tripped a code, which he could not read as he had no analog volt meter, or OBD 1 scanner. As I left the lot the check engine light went off.
That was the first visit, for which there was no charge.

The next visit was set up with a guy the owner called in that travels all around the county whom specializes in diagnosing hard to figure out vehicles.

He says it was my mass air flow sensor. He could also read the history of the code that tripped and disappeared on the first visit, which was a MAF code. Admittedly, I replaced the original failing MAF with pretty much the cheapest (~$100) remanufactured one I found online two years ago so I could potentially pass smog, which I did.

They also said their is not really a reliable way to test if the remanufactered MAF is good outside of getting one and installing it, and running it on the dyno to see if the ECU responds as it should. Also they have not had consisent results from remanufactered MAFs. Some are DOA, some work for a while, some a little longer. Is that really the case?
Is there a remanufacturer that tests their MAFs before shipping them out?
I believe the one I bought only had a one year warranty, but I'll double check, and post the one I bought for future members to see.

Now that it has apparently failed, do you guys recommend a certain brand of remaufactured MAF, that has shown to be better than another?
I can't justify spending the nearly $800 dollar price they want to charge just for the new Mitsubishi original part. Especially since I have so many miles on this engine.
Thanks again guys for all the help.
