Need Help Nissan Xterra No Start Problem

in Nissan
My 2000 Xterra started hesitating and acted like it was starving for fuel. I let it sit for 2-3 hours and it would run. Ran about 15 miles did the same thing. Looked underneith and the exhaust pipe, after the converter, was glowing red. Figured the catalytic converter was clogged. Had to get it home, after several stalls. Now the vehicle will not crank at. It will turn over, but not crank. Could it be the ECM?

You can find more using the Advanced Search tool on the right (I searched for "glowing red" in quotes).
The last post suggests pulling the codes (many auto parts stores will do that free). That may help rule out a bad crank sensor or bad O2 sensor.
I'm going to call the service dept to see if it is still under warranty and take it in. Now I'm worried I might get stuck some where.
Did you get your car check? What was wrong with it?
thanks
