random (and breif) loss of all power

[vtpsd]

I have a late 99 f250. I just brought the truck home this weekend and it made the 1000 mile trip with no issue. One time sitting idling in a parking lot (engine warm) it just stalled, acted like I turned the key off, and all the dash lights came on. Since then I have driven it about 1500 miles with no issues at all. This morning on the way to work I was cruising alonge at about 30mph in 4th gear and it acted just like I turned the key off for a second, I think I saw all the dash lights come on at the exact same time the injectors stopped firing, but it came back to life so fast it was hard to tell. I ordered another CPS just to have a spare, but it seems strange that all the dash lights come on at the same time. The previous owner installed a bully dog 4 bank chip, and I am wondering if a bad connection could cause this? It happens so quickly and so rarely that its hard to really get a good look at the dash/tach.

i pulled the ecu last night and removed the chip. I cleaned the connections a bit more and added some electrical tape to secure it. The wire for the selector was just run loosly behind the clutch pedal and looks like it was getting tugged. I routed it safely out of the way and mounted the switch in a better spot. Hopefully this cures my problem.

did it fix it? i had the same problem lsat weekend. i had previously changed my cps too try to resolve another issue (cps wasnt problem but left autozone cps in engine) this last weekend cleaned connections to ipr and ips with spray contact cleaner they had alot of oil in the connectors.while doing that i bumped the main lead going to the alt and it was excessively warm. i followed out all the wires and while i was doing that down around the starter found the passenger front abs wire on the exhaust. i also put the old cps back in while i was under there. i cleaned all my battery connections,alternator connections and found a couple of loose connections while following the leads thru. started the truck and it hasnt done it since. i believe it was a bad new cps or the checking clening and tightening of the starting charging system. could have been all the oil in the ips snesor too????

so far it has not acted up at all since I cleaned and secured the chip. It happened so rarely that, im not 100% sure its fixed, but I think that was the problem.
