4.0 Lost Power, thoughts?

It was 99 today and I drove about 20-30 miles in about 4 hours (delivery driver). I was just cruising at about 35mph when all of a sudden there was no throttle response. All the gauges were fine beforehand. Engine temp didn't go above 210-215 once. Now when I was trying to restart it the temp gauge was dead which is odd since my engine was obviously hot. My first thought is that my thermostat went out but I replaced that around 2 months ago. This happened about an hour ago so once the sun drops and my engine has cooled off I'll try starting it and brining it home.

Any thoughts/advice?

Thanks

wiggle the connectors on the PCM or just disconnect and reconnect them. sounds like bad solder joints or connectors.
