Strange starting issue
OK, on your secondary block losing power. You need a bypass SEPARATE from the start relay There are about three ways to do this
Get a "big" diode from Rad Shack and wire it from the start relay signal to the power intput of your auxiliary box to the relay coil(s)
Or fire a separate relay off the start relay signal and use it's contacts to power the box during start
Or get a late model start relay (not sure what all they fit, some Jeeps) which has FIVE terminals like this:

These new 5 terminal relays have an extra set of contacts that can be used for this purpose.
But let's make one more check-----hook everything up "normal" and with the key in "run" and the engine OFF what voltage do you have at both sides of the ballast?
And can you check the voltage going to the box without disconnecting the ECU connector? (One way is to stick a pin in the wire before it goes into the box)
