Hello, welcome. My name is***** will do my very best to assist you with your question. I apologize if you have been waiting long for a response.
Are there any warning lights coming on?
Customer: replied 3 years ago.

Not that I noticed. It only happens occasionally. I will check to see if any come on next time.

Ok let me know. Thank you.
Customer: replied 3 years ago.

could a loose battery terminal cause it? I noticed it was loose so tightened it.

Yea it is possible, a communication loss which is what the loose cable will do, will cause this type of issue.

Sorry Mike, my internet has been down. Happened again after tightening the lead. No warning Lights. Thanks. Bob

What normally causes this issue is the throttle position sensor is starting to fail or the butterfly valve inside of the throttle body is sticking from carbon debris. The first step I would suggest is to have the throttle body cleaned.

Thanks mike I will try the throttle body first. See if that sorts it. Bob

No problem thank you.
