2000 Chevy Pick-up

My 2000 Chevy Pickup Starts Fine First Thing But After You Stop Turn Off The Engine Go Into The Store Etc. When You
Try To Start It Up It Will Turn Over But Will Not Start Right
Away. Could It Be The Starter? Since It Does It When It Gets
Hot Could The Starter Need A Heat Shield?

If it is turning over good but not starting right up I would check the fuel pressure regulator. Should be a brass can like thing on the left side of the intake. Pull the hose off and if is wet with gas it is faulty.
