i'm sure it would still run as long as the engine is still getting air. when you say "no maf" do you mean, removed, replaced with ... i don't know...piping or something?
you would definately get a CEL...but i don't see why it wouldn't run....probably like shiz..

The engine will run with the MAF disconnected. I think the computer just runs the engine rich to compensate for what it doesn't know about the air/fuel ratio. This is a feature so that a totally screwed MAF won't leave you stranded.

The EEC will use a look-up table to run the engine. Has known settings for certain RPMs, throttle position, load on engine, etc. Some manufacturers call it "limp in" mode.

yes, the vehicle will run with a disconnected MAF. but that doesn't address your problem. look at your wiring harnesses very closely and see if any of the insulation is coming off, especially around the cooling fan harnesses. Also, look at the water pump pulley for possible chafing of the harness to the TP sensor. Your vehicle may be shorting VREF to ground which will stall the engine and not set a code (or CEL).
