I want to know if it’s the alternator or battery the problem. Starts no problem light do not dim while under load, but I left it idling for about half hour maybe less and when I came out side it was dead I needed to boost it back.

Hi,

If it was running, stalled, and needed jump started, the first thing we need to do is check alternator output. It is really easy to do. All you need is either a volt meter or multi meter.

Here is a link that shows how it is done. Try this and let me know the results.
