Got a dryer that only heats for about 10 minutes then will not ignite
for the remainder of the cycles.

If I put it on timed cycle it will spin for the specified time, but
only warm up once. Put it on an automatic cycle and it spins forever
after warming up once.

Shut it off, wait a minute and restart - back to 10 minutes of heat.

Sounds like a classic case of bad gas valve coils. You may be able to
find a set for about $50.
