You might have to check the wiring harness and see if you have a short. Mine kept eating CPS too. Finally got it to a real diesel mechanic (instead of parts replacer) and he found the short and had it running in less than an hour.

you have one of three things going on.....a wiring issue as lilred said above, a problem with the PCM, or even posibly a bad trigger wheel or loose camshaft bearing, some kind of mehanical cause like that. Obviously checking the wiring should be your first round of checks.....

I just replaced my CPS over the weekend because truck started cutting out. I replaced the CPS with the the grey one. Is that the recalled one? In any event, the day after I installed the new CPS, I experienced the same problem. I have had the truck for 6mo now, and never had this problem until last weekend. I have a '95 F-350.
