my 07 uplander keeps stalling. first the dash lights and radio go on and off then the check security system light comes on. Shortly after that it stalls. If you put a little gas in it, it will start. This has happened 2 times on a half tank of gas and once on a full tank of gas. Is it the security system?

 

i had a simular experiance but with mine the check engine light stayed on. I had a faulty ECU. might wanna get the vehical scaned to see if there are any codes stored in the cp. that might answer alot of questions
