Thank you for the replies. I plugged it in last night at about 11:30 pm. At 7:30 this morning she cranked right over, idled smoothly and the eng. temp. gauge read 40c. which works out to be about 110 deg. F. It got down to about 27 degs. last night. Had I not plugged her in, she would of idled real rough. It's like a gas eng. not firing in one of the cylinders. This only happens when she's cold.
