Default The dreaded Restricted performance!

Was driving on the freeway the other day when car lost power, managed to make it off and park on the side of the road. Car started once and died and it hasn't started since. The codes are P0628 & P0629 (I searched the forum with no luck). I am guessing it's either the fuel pump or the fuel pump control module. Anyone else had this issue? The control module can be had for around $30, the fuel pump quite a bit more.

Thanks, Mark

Replaced the fuel pump ($100 from Ebay) and she fired straight back up!

Bench test fuel pump first before replace.
