I drove a TR4 from Oregon to Tucson a few years back, and it kept
dying on the freeway, only to start back up again a few minutes later
with no apparent problem. Drove me crazy! In Santa Cruz, I
discovered the coil wired backward, rewired it and had no more
problems at all.

PS Did you check for hot brakes? Did anything smell/ feel hot?
