what im seeing here is that a wire is not getting power when remote starting.  Remember, when interfacing a remote start you must duplicate exactly what the key does in the ign, try using a relay and connect an orange wire(-) coming from the relay pack, (its actually a small ribbon) and connect your relay output to the brown wire.  Also make sure your pink/white wire wasnt programmed to act as a acc wire.(it can be programed in valet to either be an ign or acc)

ok, my mistake. but if there IS a second acc, brown wire, HOOK IT UP. it cant hurt, it might help. also as enice said check to make sure the 2nd ign output is not set to acc. hope it doesnt happen again.

the small little plug that connects to the relay pack.  with a relay you would connect the orange wire(-) from that small little harness to 85. 86 and 30 to 12v, 87 to the brown wire.

it cant hurt anything. i ran into a problem a while back on a tahoe where a few months after i did the install the customer called me and said here check engine light was on. i went to diagnose the problem hooked up second acc and problem solved. its wierd that it took that long to cause a problem.

Speaking of filling Gas.. About 2 years ago up here in Canada Shell changed there fuel formulas and it caused a lot of issues on the GM products.. I know the Jimmy's were affect... Caused lights to turn on and real rough running. The service dpts simply drained the tank and some other 'fuel' things (maybe change the filter) but then were fine after that....
Just an FYI

I have seen the intermittent problem you are describing several times - specificaly on GM trucks. The problem has alway been a poor connection on the white wire. The installer will test the connection and think it's fine but it really is not. It seems that this white wire must get complete power when powering up initially.
