Here's the scoop:
I recently (500 miles/1 month) ago changed the timing belt in my 01' Tundra (4.7L 4x4, 114,000 miles all original other than 1 replace 02 Sensor, one needs to be replaced). I changed waterpump, pulleys, belt, etc. Shortly after I noticed the check engine light come on and checked it (1 bank 1 O2 sensor). Did not replace it. Left it and today I went and towed my dad's Tahoe on a car hauler about 35 miles, came back to my house, had lunch and then drove over to his place (20 miles) the truck died. The A/T fluid Temp High light was on and it was sputtering as it died. All of the fluids look great. The oil was a touch low, the A/T fluid was a little high, but good color. Good antifreeze, blowing warm air. I got it to fire a little, but nothing else and it just got worse to where there was no fire eventually. The last 20 miles was with an empty car hauler and we were not in much traffic (50 mph, not much speeding up or slowing down, but we just got off a cloverleaf). Can anyone help? I pulled the negative tonight and will see if that will reset the computer tomorrow. Anywhere to start other than the code reader?
Thanks in advance,
Curtis

Wanted to let everyone know that I fixed my truck. Thanks to someone on the Tundratalk.net forum, he informed me that even though I got a Crank Position Sensor error code, that since I put in my waterpump myself, I may have routed the sensor harness wrong on reinstall and it may have rubbed on the Serpentine Belt. That is what had happened and it chewed through the wire and shorted it to the shield. I resoldered the wire and now it runs great.
Just wanted to close the loop for those interested.
Happy Holidays,
Curtis
