Most the time the engine dies while driving is due to a crankshaft sensor failure. When this fails, the engine can't be started since the ECM doesn't know the location of TDC to provide proper ignitions. Have a shop check out and replace this part then you are good to be back on the road. Good luck.
I had the same problem with my 199 cougar 2.0 4 cyl.
The problem was air in the cooling system.
I had to bleed the air out of the system, and now the heat
works much better.
I put a flushing tee between the back of the thermostat and
the heater core, and made sure that water flowed out of there.
Then I disconnected the small hose from the top of the coolant
resevoir, and poured water into it using a funnel until the coolant
level started to rise in the coolant resevoir. Then started the car, left the radiator cap off, and let it come up to temperature (thermostat open)
then over a period of about 5 minutes, periodically "goosed" the engine to clear any remaining air bubbles.
what probley happened the alternator started to heat up alittle to much and caused the belt to spin on the pulley i would go ahead and get the alternator replaaced as soon as possible. as for the lights dimming and the gauges not working you was running off your battery making the vehicle mess up i would also get your battery checked while your at it.
One thing to check is if the fuel pump is working and what the fuel pressure is. The pump is inside the fuel tank. The pressure must be 35 to 65 psi. The pump can be working but if the pressure is not enough the car will not start.
