2000 Tahoe starts then stalls WTF??

[Formula Z]

Hey guys and girls, just wanted to know if anyone has any idea why. It had a remote start but I pulled it because Its getting traded in. It did it earlier before I even touched the remote start. being very careful I removed the unit from under the dash. now again it wont start. the passlock/keyless entry has been acting up also but usually fixes itself somehow. Any ideas would greatly be appreciated.

usually won't start if its theft but try another key

it could be a bad ground somewhere in there

check the ignition leads, a loose connection could cause that, and hitting a bump or something can fix it

Well I traded it in after I finally got it started. I do beleive the remote start was starting to cause problems. Anyways we purchased 2 new 07 vehicles. I appreciate all the advice. By the way I have been hearing that aftermarket remote starts will cause issues sooner or later, is this true or does it just depend on brand and installer?? Thanks again.

all brand and installer. I have had cars with remote starts on them that are still working from teh early 90's (can you say that about the factory keyless entries?)
