If you still run a MAF then that is a possibility. I had a similar problem which was sorted by a map tweak, but that was on a Simtec & they can play up a bit.

Mafless, and no it doesn't stop when warmed up.

I'd have another look for an air leak or faulty dump valve if it's not a recuirculated type. Failing that I think your mapper needs to check it out.
