I have a 1986 ford escort.

When I drive it and warm it up and then stop for about half an
hour it loses power when I press on the gas pedal..

When the engine is increasing in speed it will suddenly decrease in RPMs.

What will cause this ?

Not likely the carb, since it probably doesn't have one in 86

My mom's Escort had a carb if memory serves me right.

If memory serves, Ford did not introduce fuel injection in passenger
vehicles or light trucks until 1984. Quite a few engines in '86 models were
still carbureted, including most Canadian and other export vehicles. If the
1986 engine was fuel injected at all, it was almost certainly CFI
(throttle-body injection). From the outside those look similar to a carb.
The simplest way to tell would be to remove the air cleaner (or whatever
sits on top) and look inside. There will be no choke plate or venturi, and
one or two large injectors will be clearly visible.

Need to correct myself, before automotive history pundits banish me from
this group forever:
1) Ford offered fuel injected engines in passenger cars at least as early as
the 5.0L CFI in a 1980 Lincoln
2) The 1986-87 1.9L engine in Escorts had a multi-port injected version
3) The 1983-85 1.6L engine used "Bosch" fuel injection. Not clear how that
worked.

This, of course, in the US. The British Escort is a totally different beast.

That was only on the GT models. I had one, and the Bosch fuel
injection was excellent. It was one of the reasons why I bought a GT
over the regular model Escort (and wrth it too).
