Hi, looking for some advise. I have a 1994 Del Sol with a 1994 B18C1 and each time I drive it the fuel cuts out at the moment it reaches normal operating temp. I can take my foot off the throttle and then give it some gas, and it revs up then cuts out. Lasts about 15-20 seconds then runs normal. I have replaced the fuel filter, IAT sensor, and O2 sensor. The dizzy, plugs, and wires are new. Vetec works fine. Just misses at the moment it hits temp. I am considering the fuel pressure regulator. Any suggestions would be appreciated.

Thank you.
