When the weather dropped the car stopped starting. it would run the battery flat if continuosley trying to start. if however left for15-25 mins starts first attempt

Restricted exhaust . Catalytic converter or muffler may be restricted .

Cold weather has an adverse affect on batteries. The clicking sound could be from the starter solenoid not receiving enough voltage to energize the starter motor. The engine being hesitant to start and run could indicate the need of new spark plugs, wires, etc.

Is your car parked outside the garage?If yes,try park inside and see any difference.

Sounds like alternator belt burned and broke.

Ensure battery is in good condition and the CONNECTION IS TIGHT. Sounds like a weak battery.

SOUNDS LIKE U HAVE A DEFECTIVE ALTERNATOR.IT WAS CHARING WHEN IT LEFT THE SHOP SO THERE IS NO WIRING ISSUE.BAD ALTERNATOR

Sounds like it could be your alternator (the part which recharges your battery while you're driving.) If it's in the process of dying, it will still give a little power back, and it will seem to be doing it's job when you're in the shop, but after some driving, you'll lose power. If it isn't that, there's also a chance it could be you have a short somewhere which is draining your battery. 
I would get your alternator checked first.
I hope that helps.
Caid.

the fuel is bad, check your fuel lines and put new fuel in. fuel does go bad if you leave it sitting too long, next time run your car for 15-30 min once a week to prevent this

I sounds by your explanation, that the belt which drives the alternator is slipping when it gets wet.
When this happens the alternator stops charging the battery, and when battery voltage drops the engine cuts out and won't start due to not having enough current to supply electrons as well as starter motor.
Have the belt tension checked, as well as charging output of alternator, should fix it.

The main computer (ECU) is directly behind the radio console. Pull carpet back on left and right sides of console. It is not the 'box' lying flat (trans comp). You should be able to take the ECU out w/o removing the radio.
