Some good advise about checking the fuel pump - see

A clogged exhaust system - go to https://www.yourmechanic.com/question/engine-run-for-a-few-seconds-then-dies-by-tom and see -

Or perhaps a vacuum issue

Clean your throttle body and MAF sensor - the MAF sensor should throw a code

Clean your battery terminals

Let us know how it goes...
