Hello your problem is simple if it is just sitting there running and you have heat but if you drive it and you lose heat it is the thermostat, it is stuck open and the fluid is passing threw the motor to fast to heat up. get a new thermostat and problem will be fixed List Search 1999 Plymouth Breeze Reilly Auto Parts
When the engine overheats it could be for several reasons but most likely a problem with the cooling system, it's never a good idea to drive a vehicle that is over heating, you could start by checking the drive belt to make sure it's not wore or lose, here's a list of other things it could be.
bad water pump
faulty thermostat
coolant level is low
faulty temperature sensor
cap on coolant reservoir not maintaining proper pressure.
you may need to have the freon charged. although its full doe snot mean it is charged. also try buying new hoses for it that are more heat resistant becasuse the hot weather

You replaced the fuel gauge stepper motor two times ? Did you do it correctly ?
Fuel Gage
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
Reviewing the fuel system description will further explain how the system functions. Refer to Fuel System Description .

Have you had the vehicle hooked to a diagnostic scanner ? Check the ASD relay ? - auto shut down relay . Relay's do go bad . The ASD relay on your vehicle power's fuel pump , ignition coils ,fuel injector's ,O2 sensor heaters etc...
take compression test
if it has fuel and spark and timming is good
compression could be low do to low oil level at one time
if commpression low need to rebuild or replace engine
CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred. · Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.
If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance
does it idle high also? i've had that problem, when i start the car (same as yours) it idles at 4.5rpms and after twenty minutes of driving for some reason goes to normal, i was told its a rpm sensor problem. good luck.
