Help! Frustrated that my 05 xlr runs for about a week then when starting it starts to sputter then die

Fellow XLR owners. I would like to say first I love my XLR and get more compliments then any car I have Owned. However, I am getting extremely frustrated when I first started getting this problem it appeared to be traced to the fuel pump module. I replaced this module from an GM(at a good expense) and got it installed by my local mechanic. It worked great for two weeks and as of yesterday it returned. any suggestions would be helpful to this frustrated owner

Have all of the fuel delivery parameters been thoroughly scanned? Have eliminated any possible sources of vacuum leaks? Are any codes stored in he ECU memory?

fixed

Thank You for thoughts. I changed the Battery and it appears to have fixed the problem. Apparently low or old battery wreaks havoc on the electronics in this car. Back to loving my xlr
