ECU or ALT or something else?

Well after reading a whack of posts. Im still unclear to what the problem is

last Weds car started left it alone to warm up. Came back to car engine was off. Tried starting it wouldnt start. Came back a few hours later car started but it was sputtering revved it died right away.

Today jumped it started right away but pretty much died when jumper cable was removed. Sputtered and sounded like garbage and wouldnt rev up.

Seemed like it was the battery when taking readings off it. Got a replacement battery on warranty put it in. Ran like a champ warmed up took it for a run to the store was all good.

Started it earlier tonight left it to warm up. Started doing the same BS and died.
My guess is the alternator but when searching the forum looked like it may be ECU but I dunno.

Just wanna have somewhat of a clue so I don't get raped at a shop.

Alright. Charge the battery. Start up the car and verify 14+V on the battery and 14 on the alternator. If the battery is not 14 or the alternator is not 14, then you probably have a bad alternator.
