Truck is stalling out 2-3 time's a week and is becoming a problem since I never no when or where it will happen.I changed my air filter to a k&n and installed a new gasoline filter.After doing some research I think it is my mass airflow sensor(MAF),I hope anyway.If anyone knows the part # I would appreciate it,or has had the same problems maybe you can help me out.THANKS

 

If you think it's the MAF try cleaning it with some electronic contact cleaner. It could just be dirty, and it would be a much cheaper fix.

Also, i see in your sig that you have a superchip. Did you check that to make sure it hasn't become loose. Just a thought.

 

I agree with pjf77 sounds like a loose super chip problem. I alos see you have a system which means you are putting a strain on the charging system. You might have a ALT. that is going shot or a loose batt. connection.
