Dying CPS or fuel pump relay?

My '00 Excursion has no history of stalling in the 50K miles that I've owned it. Last night while driving home, it just cut out. No stuttering, no rough idle, nothing. Just died. So, luckily, I coast it to a safe place. It won't restart, so I checked all of the fuses that I though may be culprits, then checked oil level to see if the HPOP was starved. I finally pulled my CPS and re-installed it (don't ask, I was getting desperate and I didn't have a spare LOL) hoping that maybe messing with it a bit would help it to run again. Well, the good news is that I got it started and almost home. It died again about 100 feet from my house and I drifted into my parking spot luckily... Now here's the questions: I know sometimes the CPS will act up for a while before it dies completely and I know other times it will just crap out. I also know that sometimes relays will take a vacation and if you smack them, they'll work for a bit. Before I cranked the truck after messing with my CPS, I gave the fuel pump relay a good whack with my ratchet to un-stick it if that was the problem. But now I don't know what's really wrong with it. Can anyone tell me their experiences with bad CPS and fuel pump relays? Thanks...

Don't bother replying. I popped a new CPS in it and the truck is running perfectly. Hopefully it stays that way...
