93 tbi cuts out when hot and wont re-start

[dazwolves]

hi all, i have a 93 astro awd with tbi that has run fine for over 12 months and missed a few times on the way to work then missed and cut out on way home, wouldn't restart. towed it to mates garage and will eventually start when cold but as soon as it gets up to running temp it cuts out and wont restart. have replaced fuel pump and filter, ecm in distributor. checked temperature sensor, map sensor. going to strip egr tomorrow just wondering if anyone has any ideas what else could be causing the problem?
i'm in the uk so parts are not as easy to get as in the usa

any help/ideas welcomed
