Default Car won't run after it gets hot. Need some input.

Well I took my car out on a cruise today. It was about an hour cruise on the highway. I didnt push it hard or anything. I pull off to wait on a buddy and it just idles real low then dies. I let it cool off for a while then cleaned the MAF and fired it back up and drove it for another hour or so. I got it back home and it did the same thing. It runs fine when its cold, but goes down hill from there. I think it might be the MAF failing or my o2's. Any input will be appreciated.

Check to make sure the coolant temp sensor is plugged in and properly working

Maybe the crank sensor is going bad?

I'll have to check the fuel pressure, but it should be good. I just put a new pump in it a few months ago. I don't think it is the crank sensor, but i'll look into it.
