After jump starting it dies right out but will start again and die out at times it will start up after jump and run fine. It will start with no jump for the rest of the day, unless sitting for hours, then needs jump will start and die out but eventually will stay started. The battery is new (couple of months). Sometimes while driving the rpms will drop suddenly from 2k to1k but go back up again quickly .I don't know if one thing has anything to do with other but when jump starting and it dies right out the rpms drop the same way only to zero.

Why are you jump starting it in the first place? Have the battery charged and tested first. Once you have a good battery, see if it will stay running and if it does, test the charging system.
