Runs fine but occasionally dies at idle
 

Last couple weeks been having a problem with my 95 850 turbo. Most of the time it runs fine but while sitting at idle it has died on me 4 or 5 times. Just all fo a sudden starts running rough like it's either not getting fuel or choking for air and then dies. I replaced the fuel filter, but it has still died on me a couple times. It always starts right back up and runs fine for a while so I can't get it to fail consistently. Seems like plenty of fuel pressure at the check valves. No check engine light at all. Fuel pump was replaced in 2003 and only has about 50,000 miles on it. Plugs, wires, cap etc were also replaced in 03. Not sure if the fuel pump relay has been replaced. Might try that next. Maybe mass air flow sensor? I'm open to suggestions. Thanks!!

Bad MAF will toss a code.
