I'm having an issue with my 01 monte carlo ss stalling.the engine runs great it just stalls once in awhile.I had the fuel filter,fuel pump and maf sensor replaced.I also cleaned the IAC module.it wouldn't start the other day and the fuel gauge showed 1/2 tank.I put a gallon of gas in it and it started right up and ran fine.it has done this twice now and I put a small amount of gas in it and it runs fine.I know I'm not out of gas.can anybody shed some light on this problem?

I suspect intermittent Ignition Control Module (ICM) failure, which will only get worse. Plug your coil packs into a new ICM and your problem should be solved. Disconnect the negative battery terminal, prior to beginning work.
