Weird problem.. need help

ok. so my rx8 sudenly shut down. no engine light came on nor other light. when i crank the engine again it turns on good and it stays like that for a while and the the rpm arrow goes down and it shuts down again.. i really dont know what the problem is. could it be the gas is no good? or the fuel injectors? this problem happend after refilling my tank with valero. :S

change plugs/ coils/ air filter?
How old is your battery? Have you had it tested?

yes change change plugs/ coils/ air filter etc.. battery about 6 months old.. test it and they said it works fine..it runs smooth but then the engine feels forced.. and if i give it gas (rpm) it goes back to normal but then again it shuts down.. i did tht twice but not anymore because i dont wana make it worse

do you have an aftermarket intake?

if so, or even if not, check the tubing for the intake...if there's a loose connection or if the tube came off...you can pull air in with the throttle down, but at idle it doesn't get enough airflow so the engine just dies w/o warning...i know...trust me

Intake pipe looks normal .. I have a question.. could it be that the engine over heats and it shuts down by it self for protection? Even though my gauge shows normal heat I was just wondering. If was it to be low comppression? What can I do and how expensive is it gana be?

Thy guys all this has really help and I really aprecciated
