Hestants then stop running on my 1999 chevy truck

Incorrect Crankshaft position and valve timing.

It has an interference engine, so the piston came up and hit the valves and jammed with piston. You now have bent valves.

Is my 1999 Tahoe 5.7 L an interference engine or not?

Hello, it is an interference engine.

..

Are you loosing fuel or spark when it stops running ?

Is it getting fuel? Does is have spark? Did it get hot?

Your brake lights and hazard warning lights should not work without the fuse installed.

have your alternator checked. your chevy is probably running on the battery which is probably only receiving a particle charge from the alternator. I had a chevy did the same thing when ever the alternator was going out.

Have you tried replacing the O2 Sensor or Mass Airflow Sensor?

Dirty trans filter,stickey trans solinoid,or your torque converter is not unlocking.If you can due it yourself try running some trans flush then replace the filter.

Run 12V directly to the motor and see if it will run, if it dosent than the motor is bad, if it does than the resister is bad, the resister makes the blower run and also regulates the speeds for the blower, but chanses are if it was making a high pitch squeel before it quit the motor went out.

sounds like the alignment on the windows is bad just my thoughts

if the wiring is good and there are no blown fuses, likely the gauge itself will have to be replaced
